I did play the fixed version :)
Indeed, now I can finally get past that gap, heh. Wall jumping worked just fine for me.
Gamplay was smooth. I just wish that you could attack while in the air. I also think that the moving platform, even when fixed, doesn't really manage to 'grab' the player along with it, when moving in th y axis.
Finally, I think that for the bug 'Dead bugs will kill you', you should really put a sprite there. Perhaps a dead bug, a wormhome or a glitchy square, anything. It just feels weird and a bit unfair when you get killed by something invisible.
Still overall, the game lets itself play, and I did finish it. Congratulations ! :-)
