I liked this game. The cutesy simple art style, the mechanic of needing to think about what abilities to use before you jump to reroll the platforms which will be solid, the level design encouraging that mechanic...
My major problem is that the dash makes you sink like a stone at the apex of the jump, and the character is slippery when they're on the ground. Making for a difficult time trying to land on smaller platforms.
Nice job, I could imagine a full game being based around this idea, with more levels, platforming fixes, and music.
