Captain Rainbow

Captain Rainbow is an action-adventure game with gameplay divided into two parts. The adventure part of the game is set on enjoying the life on the island together with its other residents. Nick can go fishing, bug catching, and help the other islanders with their requests. Most of the requests can lead to various minigames, such as boxing, volleyball, fishing, and golf.

Helping islanders would grant the player special, star-shaped crystals known as "Kirarin" ("Sparklies"). The action part of Captain Rainbow is based around those crystals. Each time 20 Kirarin are collected, a star would fall from the sky. The star could be carried to an altar at the top of the island where it would grant a wish.

The game's storyline follows Nick, who is able to transform into "Captain Rainbow", a yo-yo-wielding, tokusatsu-styled superhero that stars in his own TV show, but is no longer popular. To restore his popularity, Nick ventures to Mimin Island, an island where wishes are said to come true. Nick meets a vast array of past, minor Nintendo characters with their own dreams and wishes on his journey, such as Hikari from Shin Onigashima.

The four reviewers of Weekly Famitsu magazine scored Captain Rainbow a total of 31 out of 40. The panel was overall impressed by the game's writing and characters, especially due to the day and night cycles. They also enjoyed the gameplay, music, and tempo, but found the humor to be often vulgar.

Captain Rainbow was a financial disappointment. According to Media Create, the game only sold a scant 6,361 copies during its first week of release. A total of 22,682 copies were sold in Japan in 2008.
