I really like the cinematic touch in the beginning with the cool artwork, I think the game is a bit quiet and could of used some audio throughout just to bring a little energy to it. The idea of phasing is cool, but I think maybe it could be distinguished as some walls you can and some you cant with color or something. It is an interesting idea and I would be interested in seeing it fleshed out a bit! I imagine this was a small team if not one person working on this so its tough to do the whole thing.
