Yea, we think there's a bit not hooked up in window management when scenes transition. The dev is looking into it. I'll post back once we know more and whether a fix will be forthcoming.

I kind of get the opposite. I'll window the game so I can have a show going on as well and then it goes fullscreen when i go back to the main menu.

I play with a maximised window but whenever I either enter or exit a level the window minimises, is there any way to stop that from happening?

If you want to try the beta build now on Steam and see if your issue is resolved?
