Ok, so I like the asthetics of the game and how the jumping feels, but something about that not being able to move when double jumping sometimes makes it feel not that good, also, I'd add something like a ghost in slow-motion so that one can see how he is supposed to do that crazy stuff, after a while trying to figure out how to do that jump, button-mashing brought me up.
Nice and simple game though, but it's rather hard if you don't know how to do that stuff, tutorial could be better.
Thanks for a nice experience!
