Thanks! I'd say it has all the most common functions you'd use in Game Maker. I had written everything I needed (and more) to port Ninja Senki to XBox 360. It's not super detailed, but I listed everything in the doc file zipped with the engine.
How would you compare it to game maker with speed? Having each object hold instances of itself is brilliant. I have been working on a project like this but just had one list of objects with ok performance, but this seems far more effective. I might ditch my project and carry one with your one as I see huge potential
