Hey Twayne1,
first, thank you for playing Wild Woods and giving us feedback, we really appreciate that!
Direct 3D 11.1 should be high enough.
Maybe you can test the newest version and if the crash is not gone you can come back again? :)
For the co-op keyboard support for two players i must say, that this is currently not that easy.
Do you want two keyboards or two players on one keyboard?
