Cool gameplay idea (a bit like dome keeper), but pretty confusing to play. The dialogue thing others have mentioned is definitely really annoying, and upgrades are mentioned but I couldn't find them anywhere, i tried clicking around too (why is there a cursor in this game while platforming??) and pressing random buttons but didn't find any upgrade screen. Sending stuff home just increased numbers but didn't do anything. The first robots says it's sending me a list, but it doesn't tell me what's needed, just shows 0 for all at first, and I increase them (both mine and the city's numbers) and nothing happens. Aside from confusion, I think the main thing I would suggest improving is making the movement more interesting, at least having acceleration and velocity, but also you can do things like bounce the player when they dig, or add gravity and jumping, etc. Movement is the main thing is player does to achieve their objectives.
Anyway, congrats on the entry, it's tough to build complex things like this!
