Stencyl is a game creation platform that allows users to create 2D video games for computers, mobile devices, and the web. Games created in Stencyl can be exported to the web via Adobe Flash Player and HTML5, to personal computers as executable games, as well as onto various mobile devices as iOS and Android applications. Physics and collisions are managed by Box2D, which can be selectively or completely disabled to decrease any potential performance impact for games that don't require full physics simulation. Projects in Stencyl utilize the Haxe programming language (v2.09) and NME game framework (v3.4.2) to allow a flexible, write once, run anywhere style of game creation.
