Wow, that gets pretty frantic. I think a little more active tutorial helping the player understand the different block types and functions would help. There were a lot of different block types that seemed functionally the same - don't step on them or it's instead death. The plunger, button, and TNT all seemed the same? It was hard to tell. The graphics and animations are very nice. Music is definitely repetitive, but tows the line between obnoxious and acceptable with minor variations. The simplicity matches the rest of the game though.
Good job making this in just a few days! Well done!
