Monsters Ate My Birthday Cake has been accused of copying its map artwork from another artist, Athens, Greece-based Ilias Sounas. The illustrator posted a blog comparing art they completed in 2012 for Karios Games' MonsterUp Adventures to that of SleepNinja's game, which was funded on Kickstarter to the tune of $26,096 in February 2013 and just launched this week on iOS and Android.
"My dispute is over the game map, not the mechanics and overall style, which is identical to the world I had created for MonsterUp Adventures," Sounas told Joystiq. The blog compares the two games' monsters and overworlds, each being an island with markedly similar features such as trees, hills and shadows. Sounas began uploading his creations for the game to the Dribbble design community site in April 2012 as well as the Behance portfolio site in July 2012. Sounas said he contacted both SleepNinja and publisher Cartoon Network regarding the allegations and "their replies are pending." Likewise, Cartoon Network replied to an inquiry from Joystiq, noting the publisher is "looking into this" and "will be in touch with a response."
