Great concept, I really like the 3D planet backgrounds and chill music. As others noted tutorial text is a little much, but I dont think that should prevent you from throwing a bit of writing into the rest of the game. It took until halfway into my run that i noticed you had to sell X of a resource in 1 transaction to fulfill the contract. I was never able to fulfill any sell 15+ contracts even if all I did was sell low qualities. Feels like the Atom Smasher is a bit too limited since after using it to fulfill a contract or two the energy requirement (and cost to refill energy) is not worth it. I also had Miss Tutorial pop up before i even made my first move on the 2nd planet to tell me i was fucked and should just give up (but I ended up making quota just fine which I thought was funny). I feel like using profits to purchase buildings/upgrades between planets would mix up the gameplay.
Fun game to zone out to, promising prototype.
