Hello. I'm glad you remember me, I hope you're doing well too. I can see how challenging it can be to pass through many stars and deal with different climates, plus the fact that you have to actively manage your resources. Going this route will lead to an overall change in how the game progresses, but if it's just a challenge mode or something related, that's fine.
It took me about 3 hours to get to the point I mentioned, it's not that difficult to get there faster. The problem is understanding which auto generator you prioritize. The strategy I used is to buy everything from basic resources to final products until it got a little expensive depending on what I unlock in tech tree, for example: I bought 10 hydrogen compressors (20/s), then I started selling until I got enough money to buy the science kit. When I got some science kits, I started buying more compressors or any other equivalent upgrade of other elements;
Carbon and water are the best resources to sell. Managing energy is a difficult task for the greedy :p, if your consumption exceeds the production of one of the generators, congratulations, you're screwed. It would be nice if you reduced the price of the first sodium ion battery, the rest are fine. As it is the first version you will only have to accelerate the progression as you add content.
It will definitely be a fun game.
