This is such a wonderful and clever game. It's really smart to have the 'remove all clones' option. I felt really good after getting over that first 5 high red wall....then you get to the impossible narrow drop...and then BAM, you change shape. I personally would disable 'W' jumping. I prefer 'spacebar' (which works), but I sometimes pushed W for some reason and it got in the way. I think this is my own 'user error' though.
Really nice submission.
