I wish they were smarter too!
If anyone has some resources to point me to in how to develop some intelligence for units following you, I would really appreciate it.Implementing swarm theories seemed like overkill nor did I have the time to look at it.
For now, they just follow at a set distance and shoot once you have shot at something.
Pressing esc is also just a consequence of running out of time. A pause menu would have been a lot better rather than just killing of your person. At least you got some bonus points there (its a feature not a bug :-)
