Hey Memmiller -
I am so sorry you are having such a frustrating time with the game so far. So first of all, here is a
link to the keyboard controls. I hope that helps with that, at least.
As for your crashing issues, can you give us your PC specs as well as the output log (instructions are
here).
If it does come to you needing a refund, which I hope it doesn't, I am very sorry to say that that must go through Steam. It is something we do not have control of.
But hopefully we can help you get it sorted out.
Lorin
