this game is kicking my butt :(. I can't beat the second half of the challenge haha.
I'm in love with skirmish mode though! I've played it like 10 times already :).
I'm stuck on 35 :(.
Very fun so far though! While playing i thought of a way you could change it and make it harder hah. You could make it so the blocks have to be arranged to make a certain picture. Sort of like that challenge mode in Lumines :P.
But w/e ignore my silly suggestions! Great job on a cool game :).
