The presentation alone was amazing. The layered backgrounds, all the little particles drifting upward, the vegetation popping against the deep blues; it really sells the deep blue sea feeling. It doesn't just look good, it feels atmospheric. The flashlight getting more important as things get darker was such a good design choice too. You can feel the descent.
Combat felt good as well. The cooldown on the harpoon and dash forces you to think instead of just spamming, especially once the aggressive sharks start showing up. Early on it was rough (in a good way), but once I got into the shop and started upgrading, it felt like a full power spike. I went from struggling to full underwater Doom Slayer mode lol.
The environmental effects in the cave shop were really nice too, the subtle water ripple on the surface adds so much polish. And I like how each stage visually shifts tone. By the third stage I was fully locked in and determined to see where it was going. Then the whole Cthulu escalation and those nightmare shark-things with human skulls made things unsettling real fast lol.
The ending wrapped it up nicely and made the whole descent feel purposeful. This game was really impressive, super polished, and just feels beyond jam quality.
