Not bad. For a development period of only a month, this is impressive. The music is great, and compliments the atmosphere well. The design is simple, which isn't always a bad thing. In this case it only helps to amplify the simple nature of the game. The one flaw that needs to be adressed are the controls. They feel a bit too loose. Often I would feel like I was running on ice or jumping in low gravity, that's never good for a platformer.
