NUD is a tower defence game that will emphasize patterns in the way you build towers. The towers in the game, called NUDs, provide adjacent NUDs with various bonuses. This means that you need to come up with the optimum pattern of NUDs to maximise firepower. By emphasizing the way you build instead of relying on the usual formula of damage types vs armour types I hope to make the complexity of the game more transparent since no complexity is hidden in the creep stats or behaviour. The smooth undo/reload wave system also allows you to correct your mistakes painlessly instead of having to restart the level/game and waste time getting to the same level.
