If you still haven't maxed out your Season 1 progress, it's not too late. You can do that before October 8, which is the date when Season 2 officially begins.
After announcing the finalized date on Twitter, Mediatronic added that Fall Guys will also give out double fame points starting from today, so if you feel that you need a little boost to hit level 40, this is exactly what you are looking for.
So yeah, if you enjoyed the game so far, get ready for Season 2, as chances are, things are about to become even more exciting.
