What an amazing work! I feel like I should have paid to play this.
Absolutely everything was on point; the graphics, the sounds, the music, the controls... The only issues I noticed was that it lags quite a bit when loading areas even with a pretty powerful PC, and when above the water some of the things underwater become oddly visible.
What else can I say other than that it's a flawless entry? Congrats to all of you!
