Ah, of course. That's an option too! Thanks, BowTie. =D
I added a frame of squash very quickly just by squishing his sprite with the editor, but it looked like crap, so I took it out. That's probably because of the way I did the squashing though, not because of the squash itself. I'll try again with a better-drawn frame before I take the stretch out. Now that I look at him again, he's kind of taking a hard landing, too. I'll try adding another frame to make his face "roll" more when he lands to soften the impact a bit...
