Thanks for the bug report! Since we are working with a custom engine those problems can appear. If the issue has something to do with OpenAL, run the .exe in the troubleshooting folder. That might fix the issue.
I can't seem to find your post on our game page. I guess it's because we have a community section on the page and not a comment section. But you can go there to the thread for bug reports and should be able to post there.
I would really appreciate your help, as you are not the first who can't play the game. I hope we can resolve the issue soon. Thanks for your visit, nonetheless!
