It is honestly my favorite game so far that others have submitted and i hope you will continue working on it. i would only say
You basically implemented the upgrading system i wanted for our game that i didnt have time to make.
FIX THIS:
When i reverse, the controls become inverted. For a game id keep the standard controls
I WOULD CHANGE THIS:
I would prefer som chill vibing music instead of the house music due to the chill feeling of the game.
