Zalot, I wanted to play Vvanrim but I jumped from the treehouse into the locked schoolyard and couldn't get out again. You should fix that.
As for original ideas, I do have one. I had it shortly after I first joined Blockland, and was scripting some basic weapon edits (mostly akimbos).
Take the standard grapple knife, and turn it on it's side. Literally.
It gives a better reason to have the grapple: You are playing VERTICALLY on the side of a HUGE-ASS TOWER. Unfortunately, you'd need to script a combo weapon that can both knife and grapple, to allow for midair kills, and you'd need to replace the melee projectile on the knife with a raycast so that you can't "lead" your swing and kill someone who's five feet away from you. Then you'd need an amazing tower build with platforms that stick out, enough so that players could still fight on the platforms, but not so many to make it damn hard to swing around.
In my opinion the gamemode is ruined because of our vehicle physics.
Are you kidding that's what makes it fun.
