Preserve

📝 Summary

I led the mobile adaptation and live ops of Preserve, a relaxing ecosystem‑building puzzle game, from first mobile builds to worldwide release and post‑launch updates.

During the production, we turned critical playtest feedback on camera controls into a polished touch experience: reset camera, angle slider, sensitivity, invert axes.

The game launched free to download with optional biome IAPs, including Game Center and Play Games achievements.

Onboarding for mobile

Reworked PC‑centric controls with touch icons, fixed a tutorial placement bug, and uploaded new Android builds for iterative playtest rounds.

Added vertical text alignment passes and increased global UI sizing and button hit‑areas for phone ergonomics, safeguarded content from bottom‑bar overlap on iOS.

Camera controls were the #1 playtest pain point

Prioritized a camera polish strike team: smoother pan/zoom and refined gesture thresholds, added a Reset View button with clear UI affordance.

Added camera angle slider + optional inverted axes, introduced an accessibility setting for camera sensitivity.

Ensured camera gestures no longer trigger unintended tile/card activations behind UI.

Performance and stability

Implemented first‑launch auto‑profiling to detect average FPS and set sensible default graphics.

Raised crash resiliency via memory flags/graphics caps and regression testing on low‑RAM devices.

UI layout and shop UX

Fixed off‑center menus, increased text size in Compendium, standardized button label sizes, addressed iOS bottom‑bar safety zones.

Locked Savanna, Jurassic, Marine correctly and cleaned the IAP screen, auto‑close purchase confirmation, block single-biome purchases if “All biomes” already owned.
