Player is as light as fake killed bricks, so if you step on a fakekilled brick, it doesn't go down to the bottom of the map.
Let me see if I got more ideas...More realistic item dropping: so when you drop an item with CTRL W, they function the exact same way as the Timebomb by Melting Plastic and the PropaneTank by Rotondo.

So every dropped item is a vehicle. Cool.
Mirrors.
Mirrors can be made but Badspot and Kompressor said no because it would cause 2x lag because it has to render the game twice or something like that
