Healer bots seem a bit OP, got up to 2482 with a bunch of those. Really cool how smoothly everything moves without any real collision bugs, and it's fun to play :) I think it would be cool if you could define or pick from different formations/AI strategies for your nanobots to follow. Two things I noticed:
-Got a small bug where I pressed Space while the upgrade screen was up (it came up right as I was about to join) and it seemed to hard lock the game.
-Sometimes melee bots would path after an enemy that had gone offscreen and get stuck on the edge of the screen
