It seems that there was some sort of hangup either on the OS side or it was prebuilding some resources or something because I left it running and ten minutes later it had started... so maybe it is just a first time run thing?! Either way, I let you know if I encounter any difficulties (happy to be a test subject! ;) but usually the getting it running is the biggest hurdle! :) - looks like a fun game so far! :)
Thank you <3
