Hey, I tried the Windows and WebGL version(Firefox) and the jump only works 1/3rd of the time. By any chance, are you checking for player input in the FixedUpdate() method? (or something like that)
Also, I personally think the Chromatic Abberation is a bit too much.
I tried to play the game a couple of times but after being unable to jump, I just stopped. Ignoring that, I think the soundtrack and sprites are pretty good. The tutorial was also a nice touch.
Was this a solo or team project?
