Absolutely loved the art and sound. It has its own style both in 2d and 3d and that goes a long way. The WASD controls feel nice, including the rollerblades, although they do feel a bit slippery at times. I love the concept of an ammo delivery guy!
It seems like there's a bit of content I'm not getting after a few tries. I didn't see a thug or anything, just Boomguy. The controls also didn't lock my cursor a few of the times I reloaded, so I couldn't really turn or pick things up.
I think all-in-all, there are clear paths to turn this into a commercial game if you wanted.
