Rollquation – A Rolling-Ball Math Puzzle Game for Android (Solo Dev)

Hey HN! I'm a solo dev and I just wanted to share my latest Android game — Rollquation.

The idea was to make math genuinely fun by combining it with navigation. You roll a sphere through maze-like levels, collecting numbered and operator cubes that must add up to exact values to unlock doors and reach the exit.

I also wanted the game to feel like a nice place to be, so I built it around a nature scene with trees, mountains and a waterfall. That came with a cost though, performance on older/weaker phones was an issue during my first release. I ended up building an adaptive performance system that auto-selects a quality setting (low/medium/high/ultra) based on the device's RAM. It helped a lot, though I'm still fine-tuning it.

The other big lesson was around controls. I originally used physics for the rolling sphere, which meant the ball would decelerate before changing direction which players found unresponsive and slow. Removing the physics and making movement instant transformed how the game felt.

Unity UI is not my strength and players have mentioned that it could use some work. The UI is usable but I may end up changing it.

Any feedback or thoughts on the game is appreciated.
