Thanks to you for your time.
And your games are awesome! :3
Oh, and im testing doing the workarounds that people have found to that problem in Downwell...
Running the game with Windows 7 compatibility mode solves it.
EDIT: in any compatibility mode, from XP SP2... :P
Oh, didn't knew it wasn't common, i'm talking about fullscreen mode only showing a black screen, but the sound is going well, so it means that it's still running, i have that same problem in Downwell, so i have to play in windowed mode. not sure if it's only me... uwu
