Okay, that Blocker trick was ingenious, so I've incorporated that into the solution. As for reducing entropy - I've reduced it in some areas but increased it in others, it seems. Still, here is the new version. I'm not sure if the leftover skills will just cause confusion now.
Maybe in my pack I'll have "Save 14", while "Save 15" is a gold-level talisman. Nah, scrap that, because your Blocker trick gives the level title "Mind the gap!" a lot more meaning, and working it out will help the solution fall together.
