Hi, I am aware that the local_radius mod exists, but Pattern:Script is an incompatible fork so it doesn't seem to be possible. However, I think I've managed to fix the lag anyway. Please tell me if it helped :)
nice! going to try out the game again
edit: much better this time!
A different fork, Puzzlescript Next has the radius mod if you were to do this kind of game again. worth a check.
