Haha, I am so bad at this game. Tried it half a dozen times now and I can't get myself past stage 2....maybe I made it to stage 3 once. But this is pretty fun though regardless. Keeping yourself to a month to make the game really seems like it allowed you hone in and focus on creating a really tight gameplay mechanic.
There's a good amount of strategy in such a simple mechanic, which adds to the complexity just in the one-hit, board destroying attack alone. Then add in the power-ups and that you can only one that you most recently picked up. Yeah, it's good. Really made for some thinking on what I should do next. I also like the art you put together for it.
Great work with this!
