Just a little comment, you changed the version to 2.3 in the preloader but not in the intro movieclip. Not that its super important, but easy to miss ;)
so just a few changes that would be really convenient in my opinion. WASD movement option and different jump options. Some players are more comfortable with WASD and space for jump or something to that effect. It's really difficult for me to wall jump with the up key. Also most keyboards cant handle more than 2 arrow key requests at the same time vs 8 or 9 letter keys simultaneously. Occasionally i wont jump or something because i'm holding 2 other arrow keys accidentally and i'll die because when i pressed jump i didnt.
Otherwise great game 4/5 for me but i'll change it to 5/5 if you make some update :)
