I found a bug. I used absolute zero and all the enemies became frozen, then the battle just stopped; the enemies couldnt make a move, but I wasn't able to do anything. If it matters, Lance was also slimed at the time and natalie and anna had already moved.
Really needs some sort of main menu button, because if you accidentally click on a level, or want to stop playing a level, you have to wait until every single car goes by to quit.
One minor complaint: On one occasion, I was unable to recruit some survivors because I was out of space, but on that same day I had just finished reclaiming an apartment. Its a small inconvenience but maybe something you want to consider changing.
