I'm excited to try the new demo after following the journey for so long, but I've run into a little hiccup. Whenever I launch the new demo it opens and displays normally but it seems to launch at the wrong resolution and the cursor is locked to the center of the screen. I saw your post that you've been working on bugs, so is this one you've seen or fixed yet? Aside from that, I hope you can relax a bit after the next bug fix patch, you've definitely earned it.
Thank you very much!
The new version lets you recalibrate at any time by pressing tab, I which should help with this. If not, you could also try deleting the settings.ini file in the BE_Witches folder in Appdata/Local.
There have been other reports of cursor related issues though, which I'll definitely have to look into.
