We've got a Jekyll and Hyde situation going on! Did you make all the art? I think you did from the credits. It's really well done and was a highlight in the game. Very clean and cohesive. The animation's were a little slow and clunky though. I don't think you need to put physics on everything (if you did), but it did feel like the gravity was off and I wanted to move faster so I could get into the action of the night, but also so the daytime play wasn't so slow going.
The music you picked fit the overall tone well. I don't think you put a collision boundary on the right side of the room, because my first play I just ran off the edge of the game and had to restart and read the tutorial. After that it was a lot more fun.
I'm not sure how many jams you've done. I've only finished three, but the number one thing I've learned is that you have to build a tutorial into the intro of your game. It's so important for players understanding and enjoying their time with the game ... still, knowing how important it is, my submission doesn't have one either. I handled it with text, which is so much worse than handling it with gameplay.
Overall, this is a really solid solo dev entry and I liked my time with it. Thanks for sharing.
