I've been able to reach Level 32 and put my initials on the high score board. According to the manual, it saves a key for the last odd numbered level you complete, so if I reached Level 32, I should be able to start at Level 31. However, when I go to use a "key," it starts me off at Level 29. Why does it keep the key at 29 as opposed to 31? It may not sound like a big deal, but at this point in the game, the difficulty is very hard, so I'd like to be able to save some progress.
Also, there's a bonus stage where you have to drive through a bunch of hoops. I'm starting to get good at it. At one point, you have to cross to the other "side" and continue going through the hoops. Eventually, there are hoops near the top of the screen. No matter how hard I push to go up, I cannot reach them, and the level ends. It's as if I'm hitting an invisible wall. Has anyone else experienced this? How do I get through those hoops?
