Samples for sound effects, or streams for music. All sounds can be groups via audio buses just like in a typical DAW (Digital Audio Workstation).
All sounds can be spatial relative to the camera.

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.
Parameters are supported and values over time for shader animation.

Fragment (pixel) shader support, render to texture, MRT, easy composition and custom rendering support.

Includes a chaining graph & custom animation events for synchronization.

Automatic hot-loading of resources upon modification on disk, shortens drastically iteration times.

Integrated runtime profiler (with graphical display) to easily spot which parts of your game need to be optimized.
