Dude, what did you do. What a great level design. There was nothing to do but it didn't matter, your level was incredible.
So, so scary music, echoing footsteps, a few zombies, and you are ready to rock and roll.
I gave 5 stars on everything because the level was so good.
I tried the mic, no go. Also you need to capture the mouse in the game frame. I have 2 monitors and the mouse kept going outside the game
