I'm pretty sure I'm doing this wrong. I feel like there should be a turning point where I can summon enough minions to turn the tides on the the red dots, like the fantasies of every domestic cat in the world. I really wanted to see if I could take down one of the larger ones, but no such luck.
Also, the framerate started to chug before too long; I'm not sure if you're despawning units that move way off screen/live for a certain time, but it's probably a good idea; the game would eventually become unplayable otherwise.
