This is a lane defense game concept that I made while learning how to use unity.

I might come back to this latter and work it into a full game.

If you have played Plants vs Zombies then you know most of what you need to know for playing this game.

Additional things that you should know for playing:

   The number of Ninjas that can be out is limited and increases as you play.

   Ninjas can be moved by clicking and dragging them.

   Your units can be upgraded.

   If too many hostile mobs get past your defenses then you will be taken back to the main menu.

   There is currently no progress save system.

   If the sound is too loud for you you can adjust the volume in options.

   And yes I know that the game balance needs adjusting.
