Thanks a lot for the feedback, and its actually the opposite, Not is the only thing that can stand on the solid clones, which is what you need to do every time you want to use Not, apologies for it being unclear I did wanna create a more visual tutorial window but had to settle for just text because I ran out of time ! Thanks for playing!
For the first level Mid jump , drop a solid clone between the two platforms that you can use as your own platform , complete the level as Not as it can stand on solid clones
