the second wall jump part is criminal. its so un-responsive and afrer that you don't even have a check point. and in the part after it you will be fooled several times and fall many others, making you have to pass that part a lot of times. having to pass it one time almost made me quit the game, seeing that i had to make it several times finally did it. Sorry for the negative tone, if you can tell, im pretty frustrated jajaj.
good concept though
