It looks very good, plays really well, movement is smooth and I like the visuals. I think that tutorial fishes look a little out of place though, first level had low poly high contrast enemies while tutorial had dark high(er?) poly fishes. Swimming around, blasting enemies is great, but there should be a moment of solace in this all carnage. Meanwhile enemies are respawning and constantly chasing us, so much that I didn't have the time to read what upgrades or weapons should I pick. I really liked UI and additional skills, but that one global crash with 'R'? I thought it's also cooldown attack but I used it for mobs and then it never came back! Just before the boss fight! Also weapons disappear after going through the portal and you have to pick them up again? Couple of weapons felt weak, I was mainly sticking to spread gun for rapid fire, shotgun wasn't powerful enough even in close quarters, other gimmicky weapons weren't shooting fast enough and I felt that DPS for those was lower.
Now what I don't understand is: why shrimp? I feel that any other ship, creature or setting would be more appealing. With a wacky shrimp you might lose your initial playerbase that is looking for exactly your game but with a little more grounded setting.
I still want to go back and finish more dungeons as I didn't have enough time now, maybe with more upgrades you will get more powerful and setting will get more interesting. Sorry for being a mean complainer.
