Does the game ShadowCaster support keyboard controls?

It's common that DOS games have keyboard and some use both keyboard & mouse to play the game. But ShadowCaster seems to only be controlled by mouse - for being a FPS first-person shooter, this is quite tiresome. Anyone know how I can play with keyboard?

Doesn't the game come with SETUP.EXE or similarly named executable in which controls can be customized?

Ummm... yeah, if we're talking about the same Shadowcaster released in 93. Really mice weren't even incredibly common at that point. You should be able to use the numpad or the arrow keys for movement at the very least.
