HI,
Just some feedback. The instructions need to be easier to find. I only found them when I tried to quit the game by pressing the escape key. Even just an single line telling player to press escape for instructions would help. Entering doors is confusing. Sometime you have to press W other times you press S. I cant keep track of which button to press in which door. One button would make the game flow more. I want to be able to jump over the gap after the zombies have fallen down it, or re-enable the trap door so I can walk across it. In one room, a green enemy was stuck against the left wall. After I destroyed the first horde by making them fall through the hole, later in another room with another horde, they did not follow me through the door, as I wanted them to come into the room with the falling bricks trap. I never seemed to be able to pickup any ammo, no matter how often I replayed the game. I like the environment traps, made me think rather than just blasting everything, its more satisfying killing them using the traps than by shooting them :-)
