first 100 badges: just do nothing and you'd get them
first 200 badges: you did basically everything effortless
first 300 badges: you did some interesting stuff, nice
first 400 badges: okay now you're starting to take a lot of time to this game
first 500 badges: you're starting to have spent weeks on this game
first 600 badges: you must have started play this games for MONTHS atp,
100%ed the game: not possible, as of writing this the closest person to 100%ing the game is 3 badges away.
overall, you shouldn't really play this game unless you want puthing around difficulty badges, also a lot of badges are unobtainable now, so gl.
