So I got the game working and started running around my C: drive, just like I'd imagined - it was great! I even found a gigantic plant enemy in my SteamLibrary folder... which killed me instantly... whoops.

Anyway, when I went back to character select I saw that character was now a Skull icon, so I tried dragging it onto the "Repair" wrench button I had seen earlier - I figured this might be a way to revive the character. Then the app crashed, turning into a blank white screen with just the music continuing to play. Am I using the feature correctly? 

Oh, sorry about that! Unfortunately not, once you die there is no way to revive.

The wrench icon is there for when you go into a weird directory and the game crashes when you load it. It tries to restore it and fix the paths. We should make that clearer.

I'll look into the white screen error and see what we can do to fix it!
