I really like how you control the character in this game! It feels really neat and the way the character bobs naturally really makes it seem like they're underwater. It feels really consistent too which is cool. I never really had a moment where I felt I would lose him and didn't or where I felt I wouldn't lose him but did. It feels really clean. I think the current obstacles could use more of the control scheme though. I feel like the walls of sharks incentivize some really precise micromovements and keeping the guy really close to the centre of the circle, which is cool, but the unpredictability and wildness of using the outside of the control circle is really fun too. I think there's a lot of depth in your concept and controls that you're still able to tap into! Really neat game!
