So, even with with the dialog speed set to "Click to skip dialog", it does the same? It's really weird...
When dialog skips too fast, does all the game go to fast, or just the dialogs?
Oh that's probably the issue then. It didn't happen every time I tabbed back and forth between windows, but it's quite possible that could be the culprit. I'm on Windows 10 Home, if that helps.
I did quite enjoy the game (for the most part) and finished though. It was a very interesting/different experience as to what I was expecting initially, and I liked how it surprised me. I'm hoping to review it in more depth soon.
