I'm from Roblox

[And]

& techincally, I find it easier to build on Buildism by just dragging stuff around & letting them fill up space in a 2D area. ...That still doesn't mean I'm really accurate in my building because everything seems that fall apart when I press play or test it as my player.

However, I wonder if anyone would care if I told everyone about my Roblox username.

Maybe they are non-collidable.

No, I don't think so.
They stack up against each other and then fall apart when they're in a tower.
Maybe I'm not anchoring all 130 of them for all this time. x_X
