Thanks to my own ineptitude, I managed to die twice. I had gotten the knife and was thinking I had to run upstairs and hide, but the guy got me by the ladder.
By my third run, however, the heartbeat sound effect persisted, making it feel like something was wrong. When I died then, the game froze in the main menu, and I was unable to start the game.
From what I did play, however, the game is solid! It's a simple but effective premise, that, despite its cutesy 2D art style, manages to be quite scary at times. By my third try, however, it was more of a stress-scare than a spook-scare.
I hope you'd be willing to polish the game a bit further outside of the jam and release a longer version.
