Nice game, funny sound
I would say еhe hardest part is dashing into the button :D
and num 0 kinda unexpected choice)

Yes I wanted the button to not be too easy to push. You have to quickly double tap the spacebar from the ground or perform a diagonal (down+left) dash. I show this in the video teaser at the end ;)
I'm seeing on your screenshot that you was at 2 confidence points of the Double AirDash :)
Thanks for the comment and for playing the game !
