Interesting idea and bold graphical identity. It fits the theme accordingly ! Kudos to the little dust cloud animation when Rose or Dave land. It would've been even juicer with some sound effects !
Well done ! (I was stuck at the "i" shape with the long cloud. I got that you need to start gliding before reaching the jump apex but it was too frustrating - and the collision with the lava block seems a bit too strict)
Second round of kudos for the dust animation. :D
