-5 06 Saving the cloned glider lemming have to be the most difficult challenge in this level and the walker skill is too powerful in that regard!

. Now you can get the walker skill only at the very end.
-5 17 Those jumper+stoner shenanigans to get to the top platform is not intended at all. I added the steel block beneath the starting platform so the shimmier(or shimmier+glider) is not enough to reach the bottom. Hopefully this will enforce the left part of the solution hence all the jumper+stoner shenanigans at the middle part of the level is also blocked. (You won't have any spare jumpers for the middle part now!)
My initial gut feeling was that 6,15,17,18 would be the hardest levels of the pack when they are properly enforced and I think I was right to a certain extent.
V5.2 is out!

Level fixes:
-5 06 RefleXion - a walker is now a pick-up
-5 17 Forgive Us - reverted the latest update, added a steel block
