By the time you get to around between levels 6 and 10, it becomes impossible. The slightest hit to a barricade means you crashed and need to restart the level. The levels are pointless and not in any way possible. How can you possible turn a bus 90 degrees without turning the back where it would hit another barricade? Yet, something about this game makes you want to try and try again but you can never get it. It's really a stupid *** game
