Well honestly so far it looks like the only remaining bug that is affecting Platform School currently is that you fall through vertically moving platforms. But that doesn't happen until lesson four. I might be able to release the first three lessons until it's fixed, but then again there are some collision mask issues that could be addressed as well that could make a difference in how I present my tutorials.
So I'll think about it for a while and see. I'm probably just going to hold off on them for now though, so don't hold your breath.
Again, sorry for the delay.
