The game is fun and feels smooth in terms of progression, but you cannot play past what I would assume is early mid-game.
As the other comment states, cant scroll past a certain point from the start and it gets worse as you progress and cannot obtain uranium or storage increase once you unlock science.
Silver and coal's value gain/loss per second does not change sometimes.
Power doesn't matter? Not once did the value go to 0 or the machines stop. (I assume left value is usage per second, right being current gain or current power amount).
