1) When one players missile hits a wall both players missiles seem to be affected.
2) How can I make the players slide against the walls insted of the sticky action I get now. That is when pushing diagonally the players stick to the wall insted of sliding against it.
3) Is it possible to fire in more than 8 directions? I would like to add 30 and 60 degree fire angles in as well.
4) How could I make the missiles rebound off the walls?
