MOON CHILD Moon Child brings you back to the golden age of platform games, with detailed, hand-crafted pixel artwork, old school 3D animations, a stomping retro-techno soundtrack and silky-smooth scrolling. Guide Moon Child, a little green elf with magical mental and physical powers, on his quest to save the planet Utopia from an evil techno-virus, spread by a crashed meteor. Control Moon Child using a unique approach called Elastimotion. Your fingers will no longer miss on-screen buttons, the Elastimotion control establishes a flexible line that connects your finger with the main character. Moving your finger to the right will make Moon Child run to the right, moving your finger up will cause him to jump, etcetera. You will discover that the Elastimotion control is the most natural way of playing a platform game you've experienced on a touchscreen device. View the included demo sequence for an introduction to the game. The aim of the game is to collect at least 77 of the 84 Dark Diamonds that are spread throughout the various levels. Then you will be able to enter the psychedelic final world, where you need the Dark Diamonds to destroy the abstract heart of the techno-virus. Moon Child requires an iPad 1 (or higher) or an iPhone 4 (or higher) with iOS version 5 (or higher) to run.

Verdict
The clearest difference is price: Moon Child at Free against ArcEmu's $1.99. Moon Child also leads on iOS requirement (9.0 vs 15.5). ArcEmu's advantage is review sentiment (95% vs 57%) and update cadence (every 2 weeks vs every 15 months). On rating, ads, in-app purchases and monetization model there is nothing between them.
