Thanks very much for your reply and help. Turning off my VPN does indeed allow the game to start properly for me. As far as I can see, after trying it each way, steam offline mode is not having an impact.
I do appreciate your help. I'm glad i made the effort to find this forum. It would be great if you could arrange it so that i dont have to turn off my VPN to start this game. There are many games I play that dont requier me to do this, even including games that have a lot of online stuff happening such as Ark Survival for example, among others.
Your game is great and very original. Keep up the good work! xx
