Though we do re-develop retro games, this isn't stopping us from designing and developing some of our own games. For exmaple, the currently classified 'Project: SOUL'. We have also decided to take AstroBlast to a whole new level with the upcoming AstroBlast 2, due to it's unexpected popularity.
All of our games are developed using our own game engine: Sky Engine. This is a 2D game engine, that utilises the Android's canvas and surfaces. It can handle pretty much anything thrown at it. The engine itself is extremely close to completion, with only one major thing left to add; as well as minor updates on the sidelines. One thing we are really looking forward to doing is implementing 3D into the engine ready for the Ouya.
The games we develop are currently only for the Android platform, but we are definitely seeking to branch out to other platforms, such as PC and XBOX 360, and this is currently being progressed towards as we're gradually developing a 3D game engine in C++ with OpenGL.
