Space #4
Description
Space tiles which push the player when they move on them. Player should not be able to move, but throwing items should reverse their direction (by applying negative velocity their direction should change; depending on the speed players are travelling you may not be able to reverse course that way).
Players also need to be sucked out into space if there's an open hole into space w/ an atmosphere, but the actual implementation would be dependent on the implementation of an atmospheric system (which this issue does not cover).
