This was the first game that scared me, so well done there! The monster did get kinda annoying when it would just camp around the locker you hid in, so you had no choice to but to guess which door you need to go through and make a mad dash for it. I did not know who's name was on the tombstone and what their relation to our protagonist was.
Great work! I think 2D video game horror is really difficult, but this game does a good job at it.
