Hi,
I am also on windows 11 and it seemed to work first time for me. I am in a folder where the game has been added as an exception to windows defender.
However, I have some questions about the gameplay, minor spoilers for first safe zone.
1, when does Bob get dialogue, apart from after the first time? I don't know if there could be a way to view the building's description again if you'd like.
2, how can I get and craft tools, or does that come later? I'm still only at level 2 or so.
Lastly, I'm part of the audiogames forum, and I don't know if this game has been mentioned over there. What would you like me to do? If you'd rather I leave it, then that's fine, I won't say anything until you're ready.
