Similar to Adventure Island, you must make your way through several levels, destroying wildlife along the way, but instead of using a hammer, you have three different ways to kill them: jump on or kick them, or when they are walking on the ground, blow gas out of them.
While scrolling through the level, your vitality will decrease, but it can be restored by collecting fruit and junk food.
During your travels, you will also encounter your partner doing things that shouldn't be done in public, but sometimes, he will throw stuff at you to make you lose some of your vitality.
The only way that you can deal with him is by kicking him where it hurts.
Along the way, you can enter doors.
Doing this will give you a hint about the level and your vitality will be increased as well.
You can kick certain objects such as lamp posts, trashcans, or thin air to obtain coins, or to make hidden platforms appear.
Coins can be used in slot machines that will give you extra vitality, more lives, extra coins, and more.
Slot machines only appear when you enter certain doors.
About PC Engine
Known as the TurboGrafx-16 outside Japan, the PC Engine (1987) punched well above its small form factor and was hugely successful in Japan despite a limited Western release. Because the Western TurboGrafx-16 library is comparatively small and undersold relative to the platform's technical merits, complete-in-box North American copies are notably scarcer — and pricier — than their Japanese PC Engine counterparts.
