Thanks for playing the whole thing! Going through every system and prestiging is super helpful for me, so I really appreciate you writing all this. And I'm happy you had fun and liked the Dyson Sphere and megastructures.
Your three points are all fair. Good news: I'm already fixing them.
1. Just mining iron and rushing the sun. You're right, this is the biggest problem. In the next update, iron is not the main currency anymore. Every system now has its own currency. And the escape mineral only comes from that system's star. So you can't save it up early or rush the sun. You have to unlock the last body now.
2. Everything is too cheap to buy. Agreed. Right now there's no real scarcity. A big balance pass on prices and how fast you get materials is next on my list. I also hid the market for now, because turning everything into iron made this worse. I want you to actually choose what to buy.
3. No tutorial. Yeah, my bad. A tutorial is planned. It will explain things like the Dyson Sphere and megastructures early, so you know what they do before the end — not after you beat the game.
Thanks again, this really helps. So glad you enjoyed it. More coming!
