The SuperLem is one of the few skills that I tested out in "Practice" mode, and I did enjoy it. It takes some getting used to, but I found myself reaching for it again and again to try and get better at using it - it definitely has that compelling factor. I'm sure that the codebase has a way to track the mouse position, so making a skill respond to it should, in theory, be possible.
This one could either be done as a once-only assigner object/pickup, giving more control to the level designer and guidance to the player as to when it gets used in the level. If a skill, it's definitely a potential level-breaker, which I personally don't see as a bad thing, but others might.
Support for this idea? Thoughts? Suggestions?
EDIT: Another one to rule out as a skill. If this happens, let's make it an object similar to Radiation/Slowfreeze but one which endows a lem with superpowers, allowing it to follow the mouse pointer around the level.
