EXTREMELY linear gameplay, monotonically so. The only upgrades are bigger production, each of which is 8x the cost and 8x the production of the previous one. There's one click booster whose scaling falls behind quickly, but you're encouraged to keep clicking because it fills a heat meter which doubles your gains. Unlocking a new planet merely unlocks more of the same upgrades and doesn't even boost your click mechanic. It badly needs to live up to its own promise (in what looks like AI copywritten text presented to the player before starting the game) of interesting, unfolding decisions.
