Description official descriptions

Kato & Ken Detective Agency are assigned the task of locating a missing rich man, and you can choose either Kato or Ken to go on the mission. Your partner doesn't like this one bit, so he decides to make a nuisance of himself along the way. 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.

Adventure Island's Bastard Licensed Detective Comedy game isnt for everyone

The Good
BUT if this game is for you then it is definitely for you! Hudson is known for their generally quality titles and honestly even if you dislike this game you can't help but see that the controls are smooth and responsive, humor definitely isn't for everyone but for those who click with it will enjoy the game even more, there's quite a bit to do in this game and there are quite a few secrets across the maps and the soundtrack is just perfection! even though due to the difficulty you will likely die quite a bit, even the death jingle is catchy enough to help you control your anger! hit detection is above average, sometimes it will be really fair and rarely you might scratch your head wondering why you took damage. But overall theres lots of good in this game, now onto the bad!

The Bad
The big problem with this title is the crypticism and difficulty, now its not as cryptic as some other games but lets take the first hint you get in the game "try kicking above the stump chump", what does that mean? well soon enough you will arrive at a gap that seems impossible to jump over, near it is a stump. You must kick on top of the stump to make a platform appear, thats pretty odd even for an 80's game, although in my opinion once you understand that first clue most of the other clues that you'll find will be easily understandable it still seems kinda odd that you'd have a secret platform only halfway into the first level, and now the difficulty. This game is just pretty hard at times, i've played it daily and i still havent gotten past the first boss stage. It's just not gonna be a game for EVERYONE, if you're not into a giant yet humorous challenge. This is not for you!

The Bottom Line
honestly even with all the bad, i still dont understand why game reviewers tear this game to shreds, its not as bad as something like Darkwing Duck. It's definetly not for everyone but if it hits your mark, again you will likely be a J.J. and Jeff fan! i do kind of wish there was a remake of this, possibly with higher res and 2 player, that would make this game 5/5 for me, just imagine all the crazy stuff in this game with a pal by your side! Overall i'd recommend you should try the game at least once but i would recommend only trying it if you dont dislike the concept of this game

Trivia

Version differences

Hudson Soft decided to modify the US version of the game, so it was less offensive. Examples: * The two main Japanese guys were replaced by Americans. * The urine was removed when your partner urinated near lamp posts. * Instead of the ability to blow gas out from your ass, gamers had the ability to spray with an aerosol can. * Your partner going to the toilet in the bushes was removed. Instead, your partner just stands near the bushes wearing a bear mask.
