Wow.
I actually thought this game was really clever! One this was that I was really confused about the explanation, so perhaps try to make it clearer, maybe with a little MC with a demonstration in the Instructions section.
There wasn't much to keep me playing after a few goes, so try to make different modes or something.
I'm not sure if you already have this or not, but use checkpoints so that if the player gets to a certain level they can continue from that level (if you have used that already then sorry! I couldn't get past level 3 lol!)
Good, original game! Keep up the good work!
