That was super fun! I really like the pixel art you made for this. The game definitely wasn't easy, but I really enjoyed the risk vs reward of speeding up vs carefully navigating, and the fact that you can still pick your oxygen back up after getting hit. So there is a good reason to be towards the bottom of the screen because you get more room to avoid, but you can also be towards the top to have more chance of catching your bubbles back up. Very well thought out!
