Because there's quite a few point systems out there, I will not be adding this to the release. With the code you suggested, we'll leave out all the people that don't have the Pointshop addon by burt0n installed. Don't want that. ;_;
Like I said before, I encourage to edit the source of this addon and make it your own. Durations should be pretty easy to change. I prefer to just unstuck the player after the noclip effect finishes. It might indeed be better to kill/teleport the player if unstuck somehow fails, I will look into that.
