Trip World

Trip World is a platform game where the player controls Yakopoo, a bunny-like creature that must retrieve the stolen flower of peace, called the Maita flower. The inhabitants of Trip World turned mad in its absence, acting as the enemies in the game. The player must venture through five stages, called "worlds", each ending with a boss (and in some stages a mini-boss halfway through), that must be defeated to progress. While most of the stages are linear, some have multiple paths that the player can access to reach the boss.

The stage settings include areas such as a mountain, a jungle, the ocean and a castle. Each called: Mount Dubious, Savage Land, Ireland, Pudding Land, and Mirror Land, respectively.

The game is set in Trip World, a peaceful world where Yakopoo lives. He is a young member of the Shabubu race of bunny-like beings. Yakopoo lives with his grandfather, an old Shabubu, on the holy mountain known as Mount Dubious, where the Maita Flower is found. The named flower is the flower of peace and is deemed to have supernatural powers.

Because of this, it is usually protected by Yakopoo's grandpa, so that it won't fall in the wrong hands. However, one day mysterious shadowy creatures appear, attack Yakopoo's grandfather and steal the flower of peace. Since the Maita Flower has been removed from its place, the peace is gone and the inhabitants of Trip World get mad and don't stop quarreling with each other. In order to save his world, Yakopoo sets out to find the thieves and to return the Maita Flower.

Trip World was developed and published by Sunsoft. It was conceived by Yuichi Ueda after being influenced by Gimmick! (1992). As the programmer, Ueda had to learn to work within the limits of the Game Boy hardware.

He programmed the game so items and characters would slide down slopes. He also challenged traditional enemy design tropes by reducing the frequency of reusing enemies, and not incurring damage for the player by simply touching them. , drew his characters in round shapes. Ueda asked Narita to design Yakopoo as a chinchilla.

Upon release, Trip World has received a mixed response from critics. Staff at Aktueller Software Markt stated that Trip World was "a real treat for action fans and anyone else who enjoys a good chuckle". Video Games (DE), referred to Trip World as a "better" platform game and lauded its graphics and music. The review's author commented that Trip World is "ideally suited" for inexperienced players due to its low level of difficulty. The reviewer also praised the "clear game structure", but criticized the "missing lasting appeal" for experienced players.

Retrospectively, critics had a similar sentiment about the game. Hardcore Gaming 101 praised the game's visuals stating it has some of the best visuals on the Game Boy. However, they also criticized the game for being too easy. Marcel van Duyn of Nintendo Life was impressed with the visuals as well, but found the simplicity of the gameplay and the game's length to be lacking.

Yuichi Ueda considered Trip World one of three games he feels most accomplished with developing, the other two being Galaxy Fight: Universal Warriors (1995) and Waku Waku 7 (1996). In the latter, Ueda included Yakopoo (romanized "Yacopu") as a mini-boss. Similar to some other transforming characters from other one-on-one fighting games, Yakopoo in Galaxy Fight has the ability to shapeshift himself into whoever he fights against, providing a mirror match. A set of 19 Famicom Disk System development disks, previously belonging to Sunsoft, was obtained by a video game collector, DreamTR (Jason Wilson), and was later dumped. In one of the disks, it featured early graphic sprites of Yakopoo.

Many publications, including GameSpot, Polygon, Den of Geek, TouchArcade and Nintendo Life, have listed Trip World as one of the best Game Boy games.
