What an awesome entry!!! I loved this game so much that I want to keep playing it for much longer (please make some more levels). I loved the air depletion mechanic and the dash felt very responsive. I have to say that I at first played on the keyboard and it was not a pleasant experience but once I switched over to a controller, oh man, that was a whole new world. I'll leave here some things you might want to improve:
- When you want to push the enemies away it feels like the area from where the dash affects them is a bit to short. Maybe consider making it bigger.
- Sometimes, since the jump and dash button is the same, I dashed instead of jumping and died because of that, at first I thought mapping the dash and jump to different buttons would be a good idea but I don't think that anymore. Maybe a better solution would be to add some kind of coyote jump so if you are close enough to the ground it jumps instead of dashing.
- When you are in the intermediate levels where you get more points of air you don't deplete any oxygen. So maybe make it like you are in a giant oxygen bubble and have some different art there. I know it is the same as the actual levels due to being in a jam, lack of time, etc. but for the post jam version it would be cool.
- and lastly maybe tweaking the speed a little bit and the acceleration when switching directions. You know your business so I don't think I should explain further.
Overall this is such a great game and I hope to see a longer post jam version soon.
P.D. I think the jump sound was a neat choice and it sounds fantastic, I love it!
