hi corvine! i'm sorry to hear that. if you're only seeing black in that area, it's probably an issue with your graphics card. if you can let me know what graphics card you're using i'll be able to help you further!
hello again! sorry for the delay. i think this will fix your problem: http://www.abvent.com/support/faq/1606-how-to-change-graphics-card-settings-to-use-your-dedicated-gpu-with-artlantis-on-windows-computer.html. you'd want to follow steps 1-4, and then 8-9. then, launch "A Night Alone". at the start screen you can move the joystick left and right/press A and D on the keyboard. if you do and you can still see the graphics, just in a different color, then it was successful. if it still doesn't work, then i'll make a special version of the game that should work for you and send that over.
