The worst offenders are Kaboom, Ollie Skates and Lasagna from Heaven.
Some others that can screw you over with luck are Ratman Ralph, Rotation and Simon. To a lesser extent, Helicopter, Plastic Saucer and Space Runner.. But those aren't too bad.
Also, Frogger seems to be broken. Game ends at level 4, so there's a max score you can get, and no more.
