That was short

what's the point of the gun? if he just walks slowly towards you and kills you anyways?

it uses scratch

Seems pretty good, I actually played it through twice cause I thought maybe I could have the dude facing the monster as it arrived but I see you thought of that and he turns around during that cutscene. Noticed a glitch that occurs if you happen to click out of the game, if you click out then it wont register you clicking back in and you are left only with the option to restart.

Other than that this seems like a cool intro for stuff to come.
