Hi! I played your game on stream a few days ago! If you weren't there to watch and want to see my thoughts, check out the archived video (timestamps are in description):

Hi, sorry for not rating your game earlier.
I think a lot as already been discussed here in the comments. I'll just say that despite being quite hard in the beginning, it's immediately more enjoyable once you understand how everything works. Also it's a great idea to put options like "disable shake" in the settings, it's a great touch. I hope the development went smooth with such a big team. 
Gj to all of you guys

So cool! The graphics and sounds were great in creating an underwater atmosphere/feel. The monsters' behavior is well done, I like how they come to hit the submarine and then come back. The shop menu is cool, I like how it gets more expensive after each buy. When there are a lot of monsters it is really hard to escape them and the only thing I can do is fight🗡️ Really hard to dodge their bullets, maybe this could be somehow nerfed. It was hard to start playing well, but after a few tries, I got used to it and it was really fun. Good job!

I've lasted for 126 seconds

I love it!

The animation and gameplay are awesome, same with the sounds.

But I think I'm not very good playing it, because I can't collect hearts many, but also I'm always dying. How would I have to play it?

The game looks REALLY good! I think it would have benefited from having a slightly better bloom though, you could use some blend flags to really give illumination

nice game!

That camera shake effect is just :chef's kiss:
