Doki! Doki! Yuuenchi: Crazy Land Daisakusen

Doki! Doki! Yūenchi: Crazy Land Daisakusen (ドキ!ドキ!遊園地 クレイジーランド大作戦, lit. Thump Thump Amusement Park: Crazy Land Tactics) is a Nintendo Family Computer video game developed by KID and released in 1991 by VAP. Players control a boy with a helmet who kicks balls at enemies in an attempt to save his girlfriend from an unknown force inside an amusement park. The more damage he takes the more damage he does to enemies. The game was originally called Doki! Doki! Yūenchi (ドキ!ドキ!遊園地) in Japanese, meaning "Thump! Thump! Amusement Park". Doki (ドキ) is a Japanese onomatopoeia. The game was renamed The Trolls in Crazyland for release on the NES by American Softworks. It was to be released as Crazyland, but a change was made to feature the popular Troll dolls. That version was only released in Italy (PAL-A), and Western Europe (PAL-B). The game was scheduled for a North American release under the title Crazyland! The Ride Of Your Life!, however the publisher NTVIC cancelled it.
