Nice horror game, is not every day I play something made in Gamemaker so it was a nice surprise, the horror elements are well done and the monster design, the animations and the videotapes at the end are very uncanny and scary good job.
The game could use some better controls and maybe more time to read the instructions at the beginning but that (and a little proofreading) aside it is a very solid horror jam game. My favorite part was definitely the videotape at the end, it was a nice surprise.
Keep up the good work!
