skipping only works in the desktop version once you have seen the cutscene once, its a bit bad design now that i think about it:D
If you find the back and forth walls too difficult, you can just bounce higher and higher on the first jump pad by always holding space when moving downwards, then you can just fly over the entire stage. I was going to implement a cheat so that you could skip the hard levels if you want but didnt have time, id say that the third and fifth levels are easier than the first one. I think the levels felt easy to me cuz i know exactly how the mechanics work because i made them :p
edit: omg, i deleted the code for saving values and skipping the cutscene cuz i thought it wouldnt work in webgl, turns out it would have...
