The wall jump should have not existed I discovered it late in development and is tied to wrong coding of surface detection, I left it in there as it's not easy to find(I'm actually glad that you did :D). Thank you for your comment, I sould really try and explain objectives in my games is just that I haven't find a way to add text boxes to the games and I really like the shroud of mistery around objectives!
If you want to play it smoothely I reccomend the downloadable version, I got bottlenecked for having a way to big level for GMS 2 web version.
Thank you <3
