Declinant Snapshot
Declinant is no longer on Google Play, but this outline keeps the design/milestone notes ready for a future postmortem.
Declinant was a minimal one-touch arcade game: dodge the falling shapes, climb the leaderboard, and chase “declining” gravity modifiers each run.
Core Loop (Planned Write-up)
- Procedurally spawn obstacles in short bursts to keep rounds under a minute.
- Offer one power-up at a time so newcomers aren’t overwhelmed.
- Use subtle haptics + synth hits for feedback instead of cluttering the screen.
Features to Document
- Endless mode with escalating difficulty curves.
- Lightweight monetization experiments (rewarded ads only).
- Firebase Remote Config toggles for spawn rates and ad frequency.
- Social leaderboard powered by Google Play Games Services (now disabled).
Tech Stack
- Engine: Unity 2020 LTS + URP.
- Code: C# with ScriptableObject-driven difficulty tables.
- Backend: Firebase Analytics + Remote Config for telemetry and tuning.
- Assets: Simple geometric art authored in Figma + exported as spritesheets.
Lessons To Expand
- Importance of sizing tutorials for hypercasual players (too much text kills retention).
- Keeping APK size under 25 MB even with multiple audio layers.
- Why I pulled it from the store (support costs vs. download volume).
