Here are the list of new additions:

• LOCAL CO-OP MULTIPLAYER:
  Play the campaign mode together with a friend! The second player will take the role of a Hamspotter, a race of super intelligent hamsters that exist to help people exercising!

  Regata will keep you motivated as you advance on your workout by saying motivational quotes!
  (It can be turned off in the game settings, if you're not a fan)

• NEW BOSS:
  The Lauf Forest boss is finally implemented!
  I'll tell that this one is way harder than the Gigaschalf. Good luck facing it!
  

• OTHER FEATURES/FIXES:
  • now there's a "Quit" button
    (Derp, look how long it took me to implement such a basic thing)
  • Better step detection when running!
    (Used to trigger steps mutliple times if you ran too fast!)
  • Better navigation, cleaner menus, UI and UX were cleaned up!
  • Fixed a serious navigation bug that prevented players from navigating from the Waiver screen!
  • + Tons of bug fixes everywhere!
