It's not bad but I really wish there was a way to restart the level when you get stuck. Especially level 3 where it just start and if you don't swap the color, boom, you failed. Also, I highly recommend updating the description of the game to explain the controls, the objectives, and losing conditions to help new players understand your game better.
Still, congratulations on making that is playable on your first jam. This is something that many don't achieve and you did it! Keep at it!
