There was some glitch in PP2 where you could mess with the level code to put blocks outside of the visible window. A certain hole in this level was invisible on the PP2 site haha
A bit ashamed to admit, that I was at first looking at this: ''What the hell?! This is completely impossible!''
:))) I find it tricky. 4 some unknown reason, I just couldn't see the solution, fast. :)))
