Creepy vibe :) I like it! I read that you are planning on working on it more post-jam, so I'd suggest maybe adding some more weapons and monsters, monster variants. Like you can try to randomize the monsters sizes and speed, for example bigger ones that move slower and attack harder and smaller ones that are faster, but have less hp and attack for less. It can also be even creepier if the light around you was only forward, like a flashlight, so you can't see what's behind you and had to keep turning around. Overall it's fun! First boss almost got me cornered :) Well done, keep it up!
Would love it if you play and review my submission, thanks!
