Hey guys,
Is there any way to make this game running properly in widescreen configuration?

I've tried changing the config file (game folder) manually by modifying the resolution line, but it does not seem to bring any effects.

At least not in the game.
It's quite funny, because it seems to me that actually the game launches in widescreen (that first loading screen looks somewhat different), but then it switches to letterbox again.

Any ideas?

2D adventure games are usually fixed aspect ratio for a reason...
