FYI I noticed a couple of weird things using the invincibility AOBs above. First, it's true that it disables wall slides, but the little guy can cling to walls as if they were corners. Also, if you fall on those black spots on the floor you go through them into the grey background (and are probably stuck there).

EDIT: the wall-cling thing appears to work only on some levels.

Hacked .sol from me, all lvls completed.
Just replay the boss fight with the invisibility AoB then you'll get the hard badge

How do I defeat the last boss? :evil:

The blue guy FREEZE, red MAGMA. Put an ice block in front of of the Overlord as FREEZE, when he does the GROUND SLAM (blue target appears next to him). When he gets his hands hurt from the ice block, flame his back with MAGMA, repeat this 3 times

to do so u have to go invisible with the yellow guy. otherwise the boss gets not enraged. after a short invisible time a blue cross will appear next to him. then do like that_guy said - ice and fire

Thank you -Thompson- and That_Guy for helping me beat the last level (broken image removed)
