I hit space, I killed zombies, I ran around, figured out too late that I could rebuild walls, rebuilt some walls, got stuck in wall(?), frozen, assumed dead.
Probably pretty accurate to how my real life zombie apocalypse experience would go :D
I am not familiar with the Daleks game - is the point of the game to survive for as long as you can? Or are there other win conditions?
Using boids for zombie movement is cool - noticeable if you stand in a corner away from them as they flow around the castle like a flock of birds!
