I gave it another go, and I think I got the hang of it! I got to planet 5 and score/planet count 126 (not sure how to call the top left indicator).
From UI things, my biggest confusions were around which resources are the ones to supply, which ones are produced/stored. I always had to double check I am thinking of it properly.
I was thinking the orbits could use different colours/patterns, same for the delivery routes? The latter can blend into the other orbit’s colour. Since the routes change often it is hard to remember which ones are which, and where they’re going. Alternatively, they could be more gray and blending with the background until you hover over an orbit.
From gameplay standpoint it was quite funny, I realised I can see the game going in several different directions so it was hard to judge what’s missing while having those contradictory potential paths. I thought initially it’s going to be more of Factorio style optimisation of pipelines, but then I figured it could be more of a puzzle game, or even an idle game. So as a core it’s a cool idea and I like it how when you get access to planet 3 it dawns on you how many possibilities there are as the orbits increase. Just it also meant there are a lot of paths to take to evolve the prototype into different games, making it hard to say what’s missing/can be improved since a lot of the suggestions might be mutually exclusive. :)
