Nice work... original menu and music. Some content I havn't seen before.
Layout and progression were good. Had to go from one end to the other.

Just because you asked:
1. Not enough ammo to kill both enemies in the level. Possibly intentional that you have to run from one instead of killing him.
2. Lighting looks good except for where the dark area where the zombie is. Too dark. Got the key by pure luck and then couldn't see the way back out.
3. Lighting has no source, which is ok but, your realism is pretty good other than that there are no light fixtures. The lights come from nowhere.
If it really is your first game, I can't wait to see more. This is about the best I've seen to date. Very nice.
