The Psychology of "One More Run": How We Made Our VR Fitness Game More Addictive
How Guardian Quests transformed Squatopia from a workout game into a fitness obsession

The Problem With Fitness Roguelikes
In my last blog post, I talked about creating Squatopia - a VR fitness roguelike that combines Hades-style combat with real exercise. The goal was simple: make working out as addictive as your favorite roguelike.
But after watching players complete their first few runs, I noticed something concerning.
The Exhaustion Gap
You finish a brutal 30-minute workout. You're drenched in sweat. Your legs are shaking. Your heart is pounding. Your VR headset is foggy from the heat. And the game cheerfully says: "Run complete! Go again?"
Yeah... maybe tomorrow.
This is the fundamental challenge of fitness roguelikes. In games like Hades or Balatro, when a run ends, you immediately want to jump back in. "Just one more run" becomes your mantra at 2 AM. Those games create an irresistible psychological loop.
But those runs are 15-20 minutes of mental engagement, not physical exhaustion.
With fitness games, the barrier to "one more run" is astronomically higher. You're not just mentally tired - your body is screaming for rest. The more physically demanding your session, the stronger your psychological reward needs to be.
What Ring Fit Adventure Taught Me
Ring Fit Adventure remains one of my favorite games of all time because it understood this intuitively. Yes, it has run-based level structure, but it also has persistent progression that carries between sessions:
- Your character levels up permanently
- You unlock new abilities that stay unlocked
- You progress through a story campaign
- You earn equipment that makes you stronger
- Every session moves you forward, even if you fail a level
The genius of Ring Fit isn't just that it's an excellent workout (though it is). It's that it gives you a reason to come back tomorrow when you're too tired to play today.
You might be exhausted now, but tomorrow you'll be level 47 with that new fire attack unlocked. That's compelling. That's why people stick with it.
Enter: Guardian Quests
After seeing players struggle with motivation between runs, I knew Squatopia needed a similar system. We needed meta-progression - something that made failed runs still feel like progress.
So we added Guardian Quests, a system inspired by Hades' prophecy list.
How It Works
Remember those six elemental guardians (Blaze, Aqua, Gale, Terra, Volt, and Shade) who offer you upgrades during your run? Each guardian now presents you with a quest at the start of each encounter.
The quest is beautifully simple: "Unlock this specific upgrade, and I'll reward you with persistent resources."
These resources come in three types:
- Book Pages - Common progression currency
- Protein Cubes - Rare upgrade material
- Elemental Fuel - Premium power source
All three persist between runs. They're your long-term progression, completely separate from any individual run's success or failure.
The Genius of Optional Goals
Here's what makes this system work psychologically:
The quest doesn't force you to pick that upgrade.
You can completely ignore it and choose whatever upgrade synergizes best with your current build. The game never punishes you for making the "optimal" choice instead of the "quest" choice.
But psychologically? That quest creates a powerful secondary goal.
Imagine this scenario: You're on your first biome. You die to the second boss. Your run lasted maybe 15 minutes. In a pure roguelike, this would feel like failure - you barely made progress.
But if you unlocked that quest upgrade? You won. You completed a quest. You earned 50 Book Pages. That's permanent progress toward unlocking new abilities in the meta-game.
The Math of Motivation
Traditional roguelike failure:
- Run failed = Zero progress = Frustration = Less likely to queue again
Guardian Quest failure:
- Run failed + Quest completed = Permanent progress = Satisfaction = "Just one more run!"
Even a catastrophic failure becomes a partial success. You get instant dopamine from quest completion, instant progress toward long-term goals, and an instant reason to queue up another run.
This completely changes the emotional arc of fitness sessions.
The Smart Priority System
The quest system doesn't just randomly assign upgrades to chase. It uses a six-tier priority algorithm designed to maximize psychological engagement:
Priority 1: The Curiosity Hook
Upgrades you've seen before but never unlocked
The game tracks which upgrades you've encountered. If you saw "Floor is Lava" offered by Blaze three runs ago but didn't pick it, the system knows you're probably curious about it.
These "seen but not unlocked" quests create a powerful itch. You've been wondering what that upgrade does for days. Now you have a reason to try it.
Priority 2: The Discovery Hook
Upgrades you've never seen
Pure discovery. These quests push you to explore parts of the upgrade tree you haven't touched yet. Maybe you always pick Aqua's water abilities, but now Volt has a quest for a lightning ability you've never encountered.
Discovery quests expand your understanding of the game's systems.
Priority 3-6: The Rarity Ladder
Common → Rare → Epic → Heroic
As you unlock more and more upgrades, the priority system naturally guides you up the rarity ladder. Early runs focus on common abilities (foundational, reliable). Later runs push you toward legendary powers (game-changing, build-defining).
This creates a natural progression curve over dozens of sessions without any explicit level gating.
The Math
With six guardians per run and 300 total upgrades in the game, you're seeing six quests every session. Six psychological hooks. Six opportunities for that "quest completed" dopamine hit.
Even if you only complete one or two quests per run, that's meaningful progress. That's a reason to come back.
Randomized Rewards: Keeping It Fresh
Each quest randomly offers one of three reward types:
- 50 Book Pages - Common resource, higher quantity
- 5 Protein Cubes - Rare resource, medium quantity
- 3 Elemental Fuel - Premium resource, low quantity
This randomization serves multiple purposes:
1. No dead quests - All three resources are useful for different permanent upgrades, so no quest feels worthless
2. No farming - You can't manipulate the system to grind specific resources efficiently
3. Variety - Even the same upgrade feels different when it's offering different rewards
4. Surprise - You never know what you'll get, adding an element of excitement to each guardian encounter
How Quests Change Player Behavior
This system creates fascinating emergent gameplay that I didn't even predict during design.
The Decision Point
You're standing in front of Shade, the shadow guardian. You were planning to pick "Armor Break" because it synergizes perfectly with your Naked attack build. It's the optimal choice for this run.
But Shade's quest is asking for "Burnt Eclipse." You've never tried it before. You don't even know what it does. But the quest offers 50 Book Pages.
You pause. You think.
"Well... I've never tried Burnt Eclipse. The description sounds interesting. And 50 Book Pages would get me halfway to that permanent stamina upgrade I've been saving for..."
You pick Burnt Eclipse.
The Discovery
Turns out, Burnt Eclipse is a dual-elemental Dark + Fire favor that lets you deal dark damage to burned enemies, clearing the burn and immediately applying full damage. And you realize you already have some fire abilities from earlier guardians that can apply burn.
Suddenly you have a burn-and-detonate combo build you never would have tried otherwise. You're applying burn with fire attacks, then detonating them with dark attacks for massive burst damage. You're getting an amazing workout. You're having a blast experimenting with a completely new playstyle.
You end up beating the third boss for the first time using this "suboptimal" build.
The Lesson
The quest nudged you out of your comfort zone and rewarded you with:
1. Permanent resources (50 Book Pages)
2. A new discovery (Burnt Eclipse dual-elemental synergies)
3. A great workout (burn-and-detonate combo playstyle)
4. Progression you wouldn't have achieved otherwise (beat boss 3)
This is the kind of emergent gameplay that keeps roguelikes addictive. The quest system creates these moments naturally, dozens of times per run.
Session Persistence: How It Works in Practice
The quest system is smart about save states:
Mid-Session
- Pause your run, take a water break, come back - your quests are still there
- All quest progress persists through the session
- Completed quests immediately grant resources (instant feedback)
Between Runs
- Start a new run → new quests generate
- The old quests are gone, but that's okay - you're chasing new goals now
- Your earned resources carry forward permanently
Long-Term Arc
- Over dozens of runs, your resource totals accumulate
- You're building toward something bigger than any individual workout
- Each session is a step in a longer fitness journey
This mirrors the best roguelikes:
- Hades - Temporary boons vs permanent weapon aspects and mirror upgrades
- Balatro - Temporary jokers vs permanent unlocks and stake progression
- Slay the Spire - Temporary decks vs permanent card unlocks and ascension levels
- Squatopia - Temporary quests vs permanent resource accumulation
The Design Lesson: Two-Tier Goal Systems
If you're making any kind of roguelike - fitness or otherwise - here's the core lesson I learned:
Short-term goals create immediate engagement:
- Beat this boss
- Complete this run
- Get this upgrade synergy
- Unlock this achievement
Long-term goals create return visits:
- Complete quests over multiple sessions
- Unlock permanent progression systems
- Build your meta-game account
- Master all the content
You need both.
Pure roguelikes rely entirely on short-term engagement. They're incredibly fun in the moment, but they can struggle with long-term retention. Players might love the game but forget to come back after a few days away.
Pure progression games have strong retention mechanics, but they can feel grindy without moment-to-moment gameplay variety. Players might come back daily but feel like they're just checking boxes rather than having fun.
The magic happens at the intersection. When your short-term gameplay naturally creates long-term progress without feeling like a grind.
The Psychological Transformation
The ultimate goal of the Guardian Quest system isn't just to make you sweat for 30 minutes.
It's to fundamentally transform how you think about working out.
Before Guardian Quests:
- "I should work out today" (obligation)
- "Ugh, another workout session" (dread)
- "Did I do enough?" (uncertainty)
After Guardian Quests:
- "I want to unlock that Blaze quest for fire squats" (curiosity)
- "I wonder what quests I'll get this run" (anticipation)
- "I completed two quests, that's real progress" (satisfaction)
Obligation becomes curiosity. Dread becomes anticipation. Uncertainty becomes satisfaction.
That's when exercise becomes genuinely addictive in the healthy sense. You're not forcing yourself to work out - you're excited to see what quests appear. You're not dreading the physical challenge - you're anticipating the mental puzzle of optimizing quest completions alongside run success.
Real Player Behavior
Since adding Guardian Quests, I've noticed several behavior changes in our player data:
1. Session length increased by 40% - Players are doing more runs per session
2. Return rate improved dramatically - More players coming back the next day
3. Upgrade diversity increased - Players trying more variety instead of always picking the same "optimal" upgrades
4. Completion feedback is the most-screenshotted moment - Players love sharing their quest completions
The most telling metric: Players now complain when they have to skip a guardian encounter. Before quests, skipping guardians was optimal speedrunning strategy. Now players want to visit every guardian because that's six potential quest completions.
We accidentally made players want more exercise encounters.
Try It Yourself
Squatopia is free on Meta Quest at https://www.meta.com/experiences/squatopia-full-body-fitness-roguelike/5461039960620791/ . The Guardian Quest system is live right now.
Pay attention to how it changes your behavior:
- Notice when you pick the quest upgrade over the "optimal" upgrade
- Notice how completing a quest feels even when your run fails
- Notice when you queue up "just one more run" to complete that Volt quest
And if you're a game developer, think about your own two-tier goal system. What are your short-term hooks? What are your long-term retention mechanics? How do they intersect?

Up next: The technical deep-dive - how we built a quest system that tracks 300 upgrades across 6 guardians without tanking save file performance or breaking the save/load system.
Until then... Squat on!
