A nice game with the difficulty that's a little too high. Actually, I think the difficulty would be alright with a better control scheme. The J key for jumping feels very weird, compared to the standard up or space key. The visuals were nice, the audio was really well suited to the game as well as the sound effects and music both complimented the game.
The wall jump didn't feel very nice and a bit awkward to control. The way we got around this was allowing an early wall jump when you're not quite against the wall, which would match your aerial mobility well. Otherwise, allowing buffered inputs for characters with less aerial mobility would also work.
Overall a fun little game. Would have been nice to have been able to see if there was any content further that I missed out on.
