Overall, it's an interesting concept until you finish the solar system, then it's just menu clicking and none of the future systems really need to be explored.
The market completely negates the need to prestige. Prestige is pointless because you can build all Megastructures and all Dyson Sphere upgrades without prestiging ever. Not to mention, some prestige upgrades seem to not work. First time I prestiged, I did not get the bonus starting iron I was supposed to have.
Once you buy everything you can with voidstone, just sell voidstone in the market for iron. Because iron is the limiting factor for everything, once you have enough of it, the game is easy and way too short for an incremental game. I think the market should be removed entirely. Or later systems should have a different element as the limiting factor besides iron.
Missions tab cannot be interacted with, it's grayed out and you have to bring up options menu to close it.
Tech tree is finished in Solar system, then the button is a waste of screen space.
When you unlock the Sun, auto-miner doesn't work. But when you unlock other star systems, the escape fuel you need is available before unlocking the star, and unlocking the star is just a technicality to bringing up the escape button.
