I couldn't figure out from the description how to get it And not only me, since this is one of the rarest achievements in global statistics.

I have every building and I've clicked each one once one after another, but no matter what the achievement shows 8/11 progress. Am I misunderstanding it or something?

I'm not 100% sure but from two New Game Plus I think I got a couple Pearls between 1k-10k (I didn't pay much attention, somewhere between 4-6), but not a single one after 10k, and at the moment I'm close to 16k? Is it a bug, working as intended or is the max level distance required for next Pearl that much higher after 10k?...

Galaxy Conqueror and Boss Destroyer seem not to trigger on Steam, only ingame. The two achievements don't update for me anymore on Steam, but I have them ingame. They only updated once after the first playing session, it seems.

Just bought the game but cannot play it. Is there a setting or command line to put it not in full screen mode, or otherwise troubleshoot it? Can't even see the title screen.
