nice and simple
The game starts you out with one block. You have to collect all the chedda BEFORE you move your block into the green square. After a few levels you have to use to block wich move in tandem. After Lv.10, things get more difficult and you have plan ahead before you start moving. Good for a quick Flash fix if you're bored at work.
To author: the music sounds kind of familiar but I'm not sure.
