The jump sound definitely is something...
Interesting movement system, but it felt really uncomfortable having to jump with up and then pressing space to initiate better jump or slide.
With a little bit more cooking the movement could be something like the one in pizza tower where you have a tool for every situation but unfortunately it is not there yet.
I also didnt finish the game, i got frustrated with having to re-input slides when turning the level, and when i had to switch directions for the slide in the clouds level.
I would say there is a lot of potential for a fun platformer with fun movement options.
