When I unlocked the Berserk and Midas skills before, they said "Sold Out." Now after the most recent update, I can put doubling amounts of souls into them, but no benefit comes out. Can you please fix this?
The production of methane is a severe limiting resource, especially with how fast the price to build them increases. Perhaps there could be an early-game research project like geology but to buff methane production or allowing fuel to be made using oil or uranium.
