I think you had a very clever idea. The controls are easy to get into, and the decision to cut open the monsters trying to kill you so you can get oxygen is a great idea! I like the hide feature too. I saw the comments about generative AI. I think it can work to be consistent. If the animation artifacts are taken out with a paint program, I think the art would work great that way. This is a good concept and great job doing it. Game dev is super hard and you put together a clever concept and story.
