This was pretty fun! It was unnerving and definitely gave me a creepy vibe.
I did encounter a bug where the enemy just stood in the center of a hallway and didn't move or attack me, which made the ending a little trivial, as well as a bug where the enemy doesn't move if he sees you and chases you into a room.
Nice work on this one! Not personally a fan of pixel shaders and the VHS effect but despite that, you have a fun little game and it's worth the 10-15 minutes it takes to beat it. Keep up the good work!
