This game is sooooo addictive, and I don't know how better to illustrate that than with the fact that I just finished True Greatness, almost a month since getting the rest of the achievements. Part of me wants to be done with it now, but... there are still plenty of levels I haven't beaten...
As many others have said, game progress has no impact on achievement progress. Developer response to one of the high-rated comments from 2019 does say that the game was re-released as an "offline" version after it was taken down for server costs; I wonder if this is what "broke" achievements?
Just signed up and eager to earn my very first Badge Of The Day aaaaaand... it's for a 'game' where all you have to do is launch it and then ignore it for like half an hour. Encouraging lol
