First of all, great job with the graphics and the fog effect. Combined with the sounds like the seagulls you made a very immersive atmosphere. I thought the controls were smooth and responsive (besides the high sensitivity at the beginning, probably needs to be lower). I think the only part that really needed more work were the sharks, I kept finding myself getting swarmed by sharks suddenly and I didn't get much of a chance to get away because they were as fast as me. I think it would be more fair if you implemented a system like if the sharks didn't attack at first, maybe swam around the player in circles to "size them up" and then give an audio cue before they attack. Besides that little detail though, I think you did a great job overall! Hope to see you in future jams!
