Japanese mobile games developer WonderPlanet has surpassed eight million downloads worldwide of its puzzle-RPG Crash Fever since it first launched in Japan in July 2015.

To celebrate its achievement, WonderPlanet will be running an "8 Million Downloads Celebration" which will offer new quests and items to unlock. It is also planning to add multiplayer chat lobbies at a later date.

The game is a one-thumb puzzle game which requires players to tap on connected blocks of the same colour. It leans heavily onto anime stereotypes, with bright colours and a cast of over-the-top characters.

WonderPlanet was founded in 2012 and is headquartered in Nagoya. Crash Fever is its only game that is available worldwide.

Crash Fever has now achieved as many downloads as another "unapologetically Japanese" game, Logres: Japanese RPG, which has recently launched in the West after four years as an Asia-only release.
