To the Workers

What are they even doing...? I guess it's okay to increase them, but since I don't know what function they have, I tend to prioritize upgrading drones and such. Cheerleaders show up, but I still don't know what they're doing! All I know is that they're cute and run around busily collecting stars! What are they? Also, I can't use the saw. It's just that the sides get ground down and aren't noticeable, so I don't. But will the sides ever be useful someday? I'm hoping so. Clearing one stage a day. Let's do our best!
