The game got stuck on level 12 and i had to go back to menu to progress. The timer noise is a bit too loud and sharp. The concept is cool and if you had more time I think you could have removed many of the bugs.
I don't know what happened but when I launched the game the window was really big and I couldn't see anything. Maybe add a setting for changing the resolution? The menu was the right size though.
I think maybe you could have explained the boost feature a bit better and sort of explained how the colour values worked other than that it's pretty good for your first game.
