blitzzengine是创建一个基本的一个正在进行的项目，然而D.有效的发动机

代码说明：

BlitzzEngine is an ongoing project to create a basic, yet effective engine for developing 2D action games, aimed specifically at platform games. High performance is a key goal of this engine, as the target low-end machine is a 500mhz x86 processor with 64MB free RAM running at 60 FPS or higher. It will use the C++ programming language and by default the Allegro library for most game system functions. The engine aims for gameplay similar to Quake and classic 2D platformers for the PC. The movement will be smooth and inertia-based (although non-inertia movement will be possible), and the system will provide most everything necessary for creating a good game.
