Wow, really great work. I love the art style, I felt like I was playing an old software rendered 3D game but with fully dynamic lighting and an impossibly smooth frame rate. Sound and music were good too. The only suggestion / criticism I'd offer is that there's one sound effect, I think it's an impact sound, which doesn't fit well. Sounds like a lever or button being activated or something like that, the first few times I heard it I was convinced something had changed in the world and I hunted around to find out what. Eventually I worked out it was just me knocking into stuff :D
