Is there a way to force in-game resolution?

Hi, I know this is possible with more popular games which have config and XML files, but I was wondering if there's a way to force "The typing of the Dead" to run in a higher res than 640x480

And don't you dare make fun of me, typing of the dead is a great game You can download the demo for free, maybe someone can figure out if it's possible to run in a higher resolution.
