OH! I couldn't beat my high score! The AI is definitely improved and I didn't see any new bugs or anything. Their moving around added a bit of challenge
With the increased enemy movement I noticed myself losing sight of my white mouse on the gravel during game play causing my aim to be thrown off as I will try to aim and start shooting in unintended directions, I know some games like Don't Starve do not change the mouse but there are some games that do. It being a reticle or something during gameplay would be cool but that's also something I can change on my end.
I also noticed the enemies got very, tanky nearing wave 12. I landed what felt like 10 shots on one and couldn't kill 'em before I lost them in the swarm that was coming after me. 
The bots left UI addition is a nice touch! Wish I could have recorded a video of the last thirty second but 127 Bots bum rushing you is fairly intense!
Only bug I found, I reported already, which was the shooting oneself while moving diagonally up. Makes moving north dangerous.
