Wow, awesome job for your first jam! The gameplay was simple but fun, I particularly liked that you added an indicator to show when the enemies were about to turn around. Also the red beam really stood out from the greyscale backdrop.
I loved the character animations and the giant hand was super creepy - overall the game had quite a nightmarish quality to it which was awesome. The background music fit really well too, I definitely recommend playing the version with audio.
My main feedback is the UI was quite plain and the main menu cluttered and confusing - these may seem like insignificant things but they can go a long way to making your game feel more polished and professional :)
