I think this game has real potential but there's a few things I think would make it better:
1. More levels. So far it's been fun but I'm halfway through the game after thirty minutes
2. More enemy types. I can see the inspiration from CARRION, so I think a version of the supersoldiers or mechs would be awesome.
3. Some form of ragdoll euphoria. I think it would make it feel a bit more interesting and add a layer of depth to the game, but it wouldn't really affect much gameplay wise so that would be completely optional.
4. Better gore. Once again, it would be purely visual and wouldn't affect anything, I just think that'd be cool.
5. Easter eggs. Maybe you could add a mutation system like in CARRION to make the player stronger.
6. Voicelines/screaming. You could prolly just use something from a stock audio library for those. Something like that would be cool too.
7. Visuals settings. This is mostly just a hardware gripe, but I have played it on my school Chromebook and it runs like crap, so to accommodate for lower-end devices, a resolution option would be nice.
Other than those few things, I really love it. The movement is unique, simple, and fun, yet difficult to get a hang of in the perfect kind of way, the level design is great and well laid out, and the gameplay is engaging and very entertaining, but it feels like it could be so much better with a few tweaks. This game is very fun and worth coming back to.
