NO WORDS. GREAT GAME!!

Played it with my brother, much more fun together than alone. Good level design. More checkpoints on the long-distance horizontal jumping room to the right would be nice. Got stuck there before replaying it. Killed myself trying to figure out the jumping jacks spire, until I figured out you just let go, and let gravity do its propulsion thing ("What have I been doing all this time?"). It was a little laggy, maybe the particles effect. Dash sound repeating when you stay still on ice was a little annoying. Coyote timing would be nice.
Brother: The fire element worked nicely with vertical motion, while the ice element worked nicely with horizontal motion. Cool parallelism (or should we say perpendicularism?)!

Level design is really good. With every stage I learned the ability better and better and you chained it really well! Really good submission!
