Everything was perfect, the game play, the music, graphics, and the actual concept was interesting (following the "park a car" scheme) BUT, what really ruined it for me (and made me not try after level 3) were the controls. I hated the "stuck" controls were you had to keep turning it back so you wouldn't go in the same direction instead of it just automatically reverting to its "resting" position... but other than that, no flaws.
Chyeah. :)
