Never run from Evil Otto along the bottom of the screen.Otto will take smaller bounces and outrun your character.
If you want Evil Otto to move slower when he appears, leave atleast one robot alive. Evil Otto will move much faster if norobots are in the maze.

When firing vertically, the robots shots always come from only one side. Stand just off-center on the opposite side and you can shoot them while their shots go past you harmlessly.
Hold the Joystick in a diagonal direction toshoot at an angle. You can kill robots easily this way, as theycannot shoot at an angle.
