Hey, happy to say I completed the game. Congrats on finishing the project! Had to rename a few files, but that got me through it, no problem. Nice short experience, and yes, very creepy. If you did that custom art, awesome! It added a nice little creep factor, especially the ending. Sound design was good too. I also appreciated the decent eventing, especially in the beginning. Scenes were communicated well, and there was a lot of character motion.
So yeah, the missing assets are really going to make it hard for a lot of people to play this and give it a good shot, so definitely always test your deployed version. Lots of other little bugs detracted from the immersion a bit, but it worked well enough for a play through.
Polish this up after the jam, and you've got a really nice short horror story.
EDIT: I played again to explore all the choices. Got the jam, got the good(?) ending. Also went outside with the key and errr yup. You put some pretty awesome stuff in here, unsettling as it is. Hope more people can check it out!
