That's weird that you're unable to pick up some of the friendly robots/minions. Tho there is a cap of 3 total bots at once, I planned on adding more but time/scope creep/other stuff meant I didn't get around to it. I'm not the best at audio either so the bit that's in the game is courtesy of my friends CBSError and SeaGoatGames, who did the firing sound and the music respectively.
I'm planning to update the game post jam to get closer to what I wanted to actually get out, since the original plan wasn't the endless wave survival. It's good to hear about a few bugs I may need to patch tho, I appreciate it.
