Fun premise, great name. It's enjoyable but suffers from some balancing flaws and the lack of AI variety makes it hard to really feel threatened. The pacing suffers as the levels increase, maybe because the upgrades come in so slowly. Some more emphasis on the sound design would go a long way too. I'm only so critical because I do enjoy the premise a lot though, nice work!

Bro the music is awesome. Its like I'm playing Call of Duty underwater. 10/10

my game sorta like this but no guns

Not gonna lie, when I saw "Shop", I thought it was a literal shop that took USD and got scared. BIG relief it was not that. This was really fun! Great work! Super smooth mechanically. 

I think the enemy diversity ramps too slowly at the start. Once I learned how to not get boxed in, the game was pretty easy until those damn medic fish showed up, and then it was a big difficulty spike for me. I didn't really understand what was happening until I'd spent about five minutes or so on that single stage. Because the camera is limited, it's hard to even discover they exist since you're always dodging away, and the fish chasing you are directly in the path between you and the medics. I just thought more fish were spawning so I kept swimming around. 

I also wanted more upgrades, because I wanted more power :)

Great work!

I think the idea could work, I like how it looks and the lighting detail and attention to detail on the graphics. I think the increasing difficulty of the enemies and the upgrades keep the game having something new each time.

Even the idea you could use the money you got if you died, in a shop in the main menu to upgrade, this is also an idea that could work. Overall, I liked it.

I think it's actually a lot considering the jam time, I think it's an impressive work, good job!
