I feel the game has a lot of potential; however, I feel the biggest issue right now is the fact that death, or taking damage at all, doesn't really have any consequence to it. There isn't really anything stopping the player from just running into the lasers, dying once or twice, and then just reaching the end. I think that either changing where the player responds, or adding a damaging obstacle that can't be walked through could help fix this.
I like the concept. however, some of the blocks are being shown off the screen, which makes it a pain to find them, which I think is due to me having a smaller screen size than yours. I also think it could be better to change it so you had to directly land on the greenspace instead of just touching it.
It's a pretty fun game, I enjoy being able to upgrade the diver. My only two pieces of criticism is that the oxygen didn't really add anything to the gameplay as you lose it too slowly for it to be noticeable, and that the UI kind of blocks whatever's coming up next, though it isn't too obtrusive.
I added an updated version of the game so that UI elements such as the Borders should now scale with the screen size. Thank you for playing my game and finding that bug :)
