Nothingness

Nothingness is a new terrain type in the next Bloons Tower Defense game. It is not possible to place anything on it, and bloons cannot move onto it either. It is mainly used to create borders for tracks that are Non-Rectangular, so that the game area itself (including the menus) can still be rectangular. However, there are some tracks in which it is used in other ways. It is possible for towers to send attacks over Nothingness, if there is any case in which Nothingness is between a tower and bloons.
