Heyyy!! Your game is incredibly polished! Love it so much! Although sometimes I feel like the hitbox on the bombs is a bit bigger than expected but omg does it feel good to play anyways. A suggestion for better immersion would be for the ability to pop the vacant bubbles :) That would be satisfying! Also if you want variety in enemies, you could have the fisherman lower his hook while you're diving down, to try and catch you on the way, maybe even make deeper levels as time progresses :)
