Nice work, got sucked in a bit once I understood what I was supposed to do. I only got as far as the labyrinth for now, I may see if I can get a little further after rating some more games.
Only issue I had is that I think a few of the cards that give you fuel may have been hard to click? I was trying to click on the one that gives you fuel if you have a 0 in the ones digit and it took a lot of clicks for it to register for some reason
