Pretty fun game you have here! Definitely not the first dive/collect/upgrade game I've played this jam but for sure one of the most polished ones. I really enjoyed the little hidden areas, and the overall game loop was pretty tight. I have to admit, I hate those anglerfish lol. They're so hard to get past without them going after you! The boost and light unlocks were cool and something I didn't see elsewhere (really liked boosting!). I ended up playing for a little over 20 mins and there was still quite a bit more below me that I could see, so props on creating so much content for the game. I'll have to go back and give it another go sometime. Fun game!
Here's my gameplay video playtest if you're interest in getting some more feedback!
