Like others have said, it's a bit hard to control, but that's OK, your descriptions made it clear you ran into some trouble. I like the visuals a lot, and the music is nice. I mooshed the metal block up a bunch and can see how it will be satisfying when the hammer is swinging into it to get that mooshin'.
Maybe not what you wanted to submit, but you did a lot of great things here. Nice work!
