Thank you for creating the thread!
Considering the game's very low price, I also got the Baba Yaga DLC to show a bit more support.
So far this runs beautifully on my 670 (maxxed out at 900p). The lack of a real fullscreen mode is unfortunate, though.
Add that to the other Windows App setbacks (no FRAPS,
no Steam controller, etc) and it's quite clear this is not the best option for gaming enthusiasts with specific needs.
Another issue I have is that the App will only launch if I was at least connected once to the Internet after any reboot (I can only get my standard/stable connection in another room, so I'm 99% offline), otherwise it will go back to Desktop with no message at all to help me understand what went wrong. Good thing phones can act as WiFi hotspots.
So it comes with its fair share of oddities I have not experienced before, which doesn't make Windows Store AAA games practical to use. :/
Still, getting to play the game at such a low price shortly after release is good enough for me to consider it a cool exception!
