not sure if it's intended or not, but by pressing jump at the end of a dash, it cancels into a superjump/dash. PLEASE KEEP THIS IN THE GAME, it made the game WAYYY more replayable, alongside a small learning curve.
As long as you make a Cooldown focused build you can chain it more and more. But infinitely chainable would probably be an exploit, like in Mario. We wouldn't want that.
