Nice game! I love the simplicity!
Only things that could be fixed: are the level generation - because the end always seems to be in a straight line from the player with little in between them!
Although this would be a small change I think it would be nice if you were also able to move with your arrow keys or wasd.
The last thing would be to stop the endpoint from being an unlit color since that makes every level very simple! and if you took that away then the level generation would be fine!
These things don't need to change for the game to be good, they are just some things to think about if you are wanting to continue with this project!
