Protect the Realm

Hiya, hope you enjoy my game :).

Goal:

- Protect the 'king' tower (the one with the crown on it)
- Every tower contributes to the score per-tick, so you want
as many as possible before the zombies get too hard to bare.
- You basically want to have a kingdom of towers, all surrounded by
troops to stop the zombies getting to the towers.

Instructions:

- WASD to move camera
- SPACE to toggle whether the camera is high or low.
- Left click to 'lead' troops
- Right click to pay for (summon) troops
- You have to press SHIFT and RIGHT CLICK in order
to place a new tower.
- Press 'E' to bring the camera back to the king tower
(for if you lose it)
