Pro High performance
Written in C with high emphasis on memory and CPU efficiency.
Pro Collision handling and rigid body physics
Pro Supports desktop and mobile
Supports Windows, Linux, Mac OS X, iOS and Android.
Pro Easy post-processing/compositing for complex visual effects
Pro Custom shader support
GLSL code can be added straight into data configuration files and can be applied to any texture: background or objects whivh allows for some amazing effects. All GLSL versions are supported, again by providing the shader language version in your configuration file.
Pro Screenshot capture tool
Supports .bmp, .png, .jpg, .tga and .dds
