Very creative game. I quite like the presentation of the simple graphics and the sound designs is also fun.
Unfortunately, I found the controls to feel quite bad once you started playing the game. It was fine when you just press some buttons at the beginning (although even then the continue button seem to lag quite a bit compared to the other buttons), but when you started introducing the item placing I got quite frustrated. At first I didn't know what I was supposed to do with the "items", where I could place them or what was I even supposed to do with them. I figured out after a while that you are supposed to put them on the track, but there wasn't any indication at all that was what it was for. Furthermore, once you place an item on the track there was no way to remove it, forcing you to reset the level and watch a lengthy scene transition animation every time you mess up some little things.
