I just supported on Patreon and downloaded 1.5.4 (this happens for me on both standard and plus), but I'm unable to run the game. I can see the Celianna logo when it starts up, then it fades to black. I can hear the music and voice sfx (I'm assuming it's supposed to be an opening trailer?) but the screen stays black and clicking or pressing keys doesn't do anything. The music plays smoothly and loops at the end of the track. When I tried to maximize the window, the game rebooted itself but it just repeats the same black screen problem. I also tried closing all other running programs, but neither CPU, memory, nor disk usage is maxed out so I don't think that's the issue.
My computer is admittedly on the old and slow side, but I have no issues running the public beta so I'm not sure why the patreon version is not working. Any help would be very appreciated, thanks!
Edit: I resolved this by going to the game.exe file and running it in compatibility mode, specifically for Windows Vista (Service Pack 2). Hope this helps anyone else who may experience the same problem!
