The annoying tank controls, the bad camera angles especially when you were under attack and you moved so slowly.

Even with a walkthrough I think it was annoying to play. I seem to remember something about a lantern and the level of fuel it had. If it wasn't full later in the game, I believe you couldn't continue and I can't remember if the game had a save and load system.

I'm sure someone will correct me. It's been a while.
