I've played more than half of the games so far and all of them are so confusing (including mine). So nice to see that this game is easy to understand, while hard to master. Maybe you can implement the saving of the highscore (using Playerprefs), but other than that it was great. I managed to get a highscore of 57, but I see you have a highscore of 184 so I think I'll go now.
