The main changes from V4 are to disable the weapon and ammo scripts which show weapons and ammo and to add two sprites to act essentially as switches - so, if a player goes to the correct place then a block will slide to unblock a path. The behavior could be used like a pressure pad which moves a remote block or to represent a player being in the correct place to push a block aside where the block can only be pushed one way. This game uses the remote switch analogy. Note that the block will not interact with the player like a physical object being pushed around, because this could result in the block or the player being trapped against against the wall of the maze ) The maze cannot be random because the blocks have to be positioned within a certain maze
