I had created a "demo" version of BROK for the Steam Next Fest this summer.
This was only for technical reasons and has the exact same content as the free Prologue.
So I am deactivating this duplicate. If you didn't play the demo yet, please download the Prologue instead, which also allows you to review it (contrary to the demo!)
