Hey there! I'm not too sure, but it looks like that has to do with corrupted or missing files. I went ahead and uploaded an installer for the game that you could try.
Cool, glad that worked!
You cannot move the van, at least not at the moment. I honestly didn't expect this many people showing interest in this game- I've just been making one small prototype every week, and this is one of them.
I'm bringing two other people in to turn this into something more, so stay tuned! :)
