Beware their leader. And long time ago I wrote something I've planned for it.
PS. On a side note, have you noticed any speed decrease from the v0.376 to the last demo? (I mean the one with wolves and roaches). I'm actually asking for general speed, not only when the bunch of roaches appear.
I'm working in some changes to improve the game performance.
PS2: For those having problems with the previous version, here I upload a version with a slight improvement of the depth algorithm. This ZIP file contains both versions for windows, in order to compare them.
