Yeah they say you can only use a certian number of blocks but it lets you finish even if you used more.

did you do it with yellow or green dots once you completed it, yellow means perfect while green means you did it with more blocks then needed, but you can do some with less blocks then they say and you still get a green dot, :stupid:

Done, pretty easy once you get a pattern down.
