This was pretty damn fun! I liked the atmosphere, the simple core gameplay loop, and the jokes themselves were the best form of humor: puns!
A couple of things I'd like to see in terms of QoL stuff for future game proejcts, if you stick with these types of games.
I'd love to have a stamina bar to show how close the player is to being out of breath, it's a little tough to keep track of. I'd also love a checkpoint maybe halfway through, just to save time on replay if you get killed or get stuck in the level! The level has a few points where the player can be stuck in the world, and I had to reload to get free. Not a huge problem.
For a game jam game, this was excellent and you should be extremely proud of how you did. Amazing work, keep it up, and I can't wait to see what you make next!
