Thanks! I'll look at adding another way out, maybe down a stairway or something like doublecross does. I thought about adding another spawn room, but it would have to be off to one of the sides and I sort of want it to be centralized to give easy access to either route to the intel. I'll fool around with it.
Now I'm working on widening halls and doorways where I can. I may remove the angled stairway when you go in the right side as it's a little awkward and gives maybe too easy access to the spawn area for attackers. I might replace it with a hole that defenders can drop down like they have on the other side.
Next release should have backgrounds, sounds/soundscapes, and be somewhat optimized, though it seemed to perform alright.
