Cool idea, and nicely done maze generation. However, the controls felt quite janky and inconsistent to me. Are you using Transform.Translate for movement? I was using that for my game and found that movement felt a whole lot faster in builds of the game than in Unity’s testing window. Perhaps something similar happened with your game?
The controls would be fine, though, if not for how walls trigger an insta-game-over. I might suggest that there be an alternate “easy mode” (or perhaps call the current one “hardcore”) where the walls don’t kill. Or perhaps different difficulty levels, the easier ones giving the player a smaller hitbox.
Due to the control issue, did not win the game :( However, it’s an interesting idea that put me in mind of those metal-ball-in-a-maze thingies, which I like, and the procedural maze generation was quite nice. So good job!
