Very interesting game! The aesthetic is very nice and fits the gameplay very well.
And yes, no idea how you make the survivor AI but it sure is very good! It seems to know when to run and when to stay still, almost sentient. Super cooool!
I found some bugs, it seems if you enter the game and stick around in the menu page for a while before playing, the serum/sec will be higher as it built up from the survivor shooting in the menu page. (or so I thought, I'm not sure)
Nice touch on the menu page though. Very active and clever!
Hooopefully no one beat my time anytime soon
