Well at first I thought: oh what an interesting mechanic, you can fart your guts out to gain some height! I guess it kinda makes sense that it would kill you after a few of those nasty taco bell waterfalls! Really great take on the theme, really fitting music / atmostphere (reminded me of the Doom sountrack!). I think you could have gone a bit further in respecting the 64x64px resolution because most of your gameplay actually fits in there. I also would change the ability keyboard map to space x2, a bunch of times I have accidentally used my ability when I just wanted to do a precise jump. Really cool idea and great execution overall!
