Man this game is tough - I made it to the top of screen 3 (I think) before running out of oxygen, I couldn't beat it but it was a fun and tense experience, love the climbing animation and particles looks like you guys put a lot of care into the artwork, one thing I would prefer would be the freeze potions freezing the lava even if they don't land directly in it, I made it through the entire first screen without needing them at all, but having to wait for the lava to reach an area you know it will freeze so you can get the oxygen puts yourself in too big of a risk in my opinnion - Still I had a lot of fun even if I couldnt beat it
