Fun little horror game! Horror has a special place in my heart, and this definitely creeped me out. The feeling of not knowing what or how things will happen but anticipating SOMETHING is going to happen. I feel like you did that wonderfully.
If I gave a critique, I would say the level design needs some more thought. I know the blood and dirty environment adds to the creep factor, but if your goal is to make a good story within the horror game, I would say add some 'brightness or cheer' to it to REALLY contrast when the horror aspects come into play. Make the player feel safe...until they're not. That being said, I know this was done in a short game jam. You did more than I could in this short of a time. I followed you on Twitter to keep up to date with any games you make!
