Region-free. Will work on UK/EUR/US consoles.
There are 5 levels in total, with a boss at the end of each, as well a mini-boss in the first level.
Pikachu can jump on enemies and use a special move which clears all of the enemies on the screen, although the latter can only be done when the charge meter is full (indicated by a numeric counter)
The player can start either 3 and 5 lives and continues each, and there's a difficulty setting in the options menu.
