Well considering the stage of the game I've gotten as far as I could. I was going to try to see how the bombs work, but requiring hydrogen was an oversight. It makes sense and isn't a big deal, other than not being able to transport O2 or hydrogen... which was another oversight on my part. Transporting water is fine though. The only problem is that it's impossible currently with how aggressive the enemy is to take control of asteroids after they start to infest your area, they just simply reinfest right after a bomb. I was expecting to be able to designate a target or just launch them when I'm ready to clear multiple out at once, but that was another oversight that I wasn't expecting I wasn't going to be able to do. Can't wait to play after the balance patch comes. I'll go back to expanding before T3 Tech.
Splitters or Filters that only accept a designated resource type would be great additions and looking forward to the pipe rework you plan. Drones as well, would be a good T4 or T5 Tech anything that saves room. I don't know how you plan for Drones to work, it'd make sense if they were solar-powered requiring to charge after X amount of period.
I actually really just enjoying thinking about the potential of this game. So it's easy to just want to comment thoughts about it. Certain Ideas are probably outside the scope of potential, like collision between asteroids; or just orbit around the sun. I'm sure satellites are reasonably achievable. I would like to think about what kind of Lore you can cook up with this. Could the Redacted be sentient and could they just be something that slumbers, maybe within the sun until you start generating a certain amount of activity. Maybe an end game goal like a Dyson Sphere or a Stellar Engine could be a good End Game Objective. Maybe you could implement Data Logs for each new Tech Level giving tips and develop a little story.
