This is a fun platform puzzler, with some really nice mechanics. Though, on my second playthrough, on the second level, one of the scaffolds fell on my character and trapped him in the ground, making it impossible to move. When I restarted, it gave me a single 1x2 scaffold instead of 1x6 from the previous playthrough, making the level impossible to win.
Good ideas all around, but the implementation could use some work. Nice graphics and sound. With some more work this one could be really good.
