Hi again AFG! I wanted to play your game too, and I liked it a lot, specially the concept of automating resource generation and the decission between going for more hexagons or using the credits to upgrade your current ones. I only have two small nitpicks: I think this game would benefit more of a more clear goal (reaching 1 million credits or something like that?) and automation should be more enjoyable: it felt a bit clunky having to pick the resource and only then the automate option, or having to do it again if you run out of energy.
Other than that, congratulations for creating a game so complex in so little time! if you want to keep working on this idea, think about creating options for sinergy between hexagons, like an upgrade that increases the production of x resorce of neighbour tiles (maybe there is some similar already, sorry if I missed it).
