This is a great game and I love the art style and the fact that you guys put the theming into game mechanics! I feel like the main mechanic of going beneath the surface is a bit janky since a) it's not very intuitive [although you guys did put it in the itch page description] and b) the timing is awkward and it's not very lenient towards the player. I think the music fits great as well as the sfx. Most levels have good design but some like level 7 (dive to white platform is straight ragebait compared to other levels) and level 5 (jumping is not very intuitive, and it would feel better to reverse the up/down controls imo where down jumps, but the control thing is minor) could be better. Overall, great game! Good luck!
