I liked the art, gameplay loop, and the concept. I was able to understand quickly what needed to be done. The movement probably could be a bit different so it would be easier to control. At times, I got confused between turning right and left. At first, I thought I had two floaters but as I kept trying out various buttons to trigger the floater, I realized that 2 was actually the input and not the number of items. You could add visual feedback to convey that player took damage when jellyfish is touched. The UI served well in conveying information about oxygen, health, and depth, but you could explore options for conveying all or at least some of that info through in-world objects so it would feel more immersive. Overall a nice game and I am adding it to my collection. Please check out my submission to the jam.
