your game is working well, here is my feedback...
- good presentation on start screen
- good 3d graphics
- music doesn't quite match the vibe of the game
- the first level should not have an enemy, let the player learn controls
- if you make the coins spinning it will look better and they will read better as coins
- when
- this would also create level progression, dont throw too many things at hte player at once
- level 1, no enemies or holes, just coins (practice moving)
- level 2, coins and holes, no enemies
- level 3, coins, holes and enemies.
- move variety would help to keep the levels interesting
- add more types of objects and mechanics
- create more interesting paths and mazes
- swap in different colors and patterns
- i see in the screenshots there are several other level types but i didnt get that far, maybe introdce more new stuff earlier to keep players interested
