The game is good, and I believe you are inspired by Miziziziz's Endoparasitic. The way the gory art style when humans are dying and the way the controls feel (if it is better) feels quite similar. I like the level, but I wish you can make the barriers to be a bit more precise. For example, from your second and third examples, those small boxes are one giant wall, but it feels like the player can squeeze through that gap. But the realization hits and apparently it isn't.
I like the monochrome aesthetics, but the sudden red blood gives it away. Maybe you can choose a different color that isn't red, but close to it. Then, it will look a lot better. Overall, good submission. Looking forward on the future.
