i have finished making another version of castle defense. z to shoot and arrow, x to shoot a bomb. mouse to aim. this is only the second version, so it isn't that good. the leader of the enemies in the begining is invulnerable to the bombs. the red guys move faster, and give more points. the catapult is sort of glitchy, can anyone tell me how to fix it? Please tell me what I should add, and what I should change. The next version will include a way to die, and the catapult will do damage.
