This really needs some tasks automated i just found out there are around 10,000 planets in my supercluster and i have only discovered 1/5th of them so far. i already own 150 planets and am a bit overrun already.
The one time upgrades should really be rebalanced as well i dont see the need to speed up construction by 1000 hours or even 32 hours i would much rather have more options for the construction for all buildings and the same applys for the overclocking as well
The performance starts to drop alot when you have alot of bulidings which are mining at a very high level. Perhaps you could implement some sort of counter instead for the planet to increase performace. I have noticed that the collect all does work propely either at times. Some way to create templates of what to build on planets could also be great its quite boring going into lots of them to choose what to build. You also dont have the shipyards in the mass upgrade section. Some way to sell all the gems at once would also be good the inventory starts to fill up very quickly later in the game.
