iOS developer Jiang Zhi may have worked out how to sneak a copyright-defying Super Mario clone onto the App Store: make no reference to anything Nintendo-related in its title.
Hence, presumably, 3D Cartoon Land: Safari. It's a fairly inocuous-sounding name, although a quick glance at the game's screenshots exposes its true, evil roots.
Koopa Troopers are remodeled as "angry tortoises", while Goombas resemble small shuffling pinecones.
The Mushroom Kingdom's trademark "?" blocks are now "!" blocks. Mario himself has the dead eyes and stiff, poorly-animated arms of a brightly-coloured cadaver.
"Very simply yet very addicting, this unique game requires you to quickly jump over obstacles and collect coins," the game's official description reads.
"But you are not secure in this beautiful cartoon world. An angry tortoise could bite you. An easy and smooth control makes it very funny and to jump or run."
It's not the first time a Nintendo game has been cloned on the iOS app store. Thousands of gamers downloaded a fake version of Pokémon Yellow last year, while Mario Kart rip-off Mole Kart was left available for weeks.
3D Cartoon Land: Safari costs just 96p. We encourage you not to download it.
