Funny game with an interesting mechanic, but it's super hard!! Don't forget you're the only "A Small Game About Dashing" expert right now :D That's pretty common in jam games, but maybe you should give more time at the beginning, or slow down things a bit. It's cool to give informations in the beginning but maybe that's written a bit small.
Other than that, really cool idea, I think the game would deserve a bit more polishing to be even better. Congratulations!
