I could live with that. It would actually use less code since it is independent from vertical flips like they are used in ERZ. I guess I will wait for some more suggestions but if nobody comes up with a better idea I see no reason for not changing it that way (yay for double negation).Or you could make the player not lose any height while performing the maneuver. That way, it would be kind of like a hybrid between thok and glide.
I was also thinking about making telekinesis pushing yourself away from or pulling yourself towards nearby bosses since right now it has no effect on any boss for obvious reasons. Has anyone tested if telekinesis works on nearby players, too? It should work but I wasn't able to test it properly by myself.
