Good loking platforming game that I SUCK at ;P
The second level was already too hard for me. I don;t even know what the game wants me to do because I cannot seem to get the height needed to make the jump in the middle of the level.
The music accompanies the frantic gameplay nicely and the art looks very good.
It's a shame the game is so hard, because I didn't even get to the scaling part and reading the comments I am not alone in finding the game very difficult. For a game jam I would either err on the side of being too easy than too difficult or have a difficulty slider, or ramping up the difficulty more slowly after players at least saw all your game has to offer.
Still a great game though, I just suck at it ;P
(I did get kinda close to your level 1 time at least !)
