Wow, really great! There was a problem regarding the size of the game screen and the page for me. Maybe you could check the PlayerSettings in Unity and match it to the page on itch? I don't know if that would solve it. I was able to check the page only after zooming to a 60%.
I hadn't read the controls on the page very well, so when the first cut scene happened (the trip to mars) I was a little confused if I had to do anything. Maybe keep an instruction on the screen: "press 'E' to skip".
I loved the soundtrack when in Mars. Atmospheric, but jazz, so very connected to Earth, right? That's unexpected and adds to the depth of the game. The first time I loaded I think there was some kind of smooth jazz playing in the menu and people talking!
Gameplay is great, enjoyed the perspective choice.
Very ambitious idea, I don't how many people were involved in this, but you showed you can set huge goals (a building system? wow!) and deliver them!
I agree you could have polished the art a little more, maybe using some abstract particle as the resource... (Where did the gears come from?). I couldn't keep playing because it was unclear for me how long the gameplay would take. When I got back, I had that resolution problem once again.
Great effort! Thank you for your time in making this.
