This is a cool game. It is spooky and simple to play. I played twice and didn't get all the areas, on my 2nd try I think I had 2 or 3 left to get. Both times ran out of fuel.
I think some kind of map would be helpful maybe that just shows where you've already been.
It is nicely spooky, and the artwork is lovely. Was the Van a 3d sprite?
Solid game and I think this could become something very interesting.
