    C-Lesh and SMW Engine

    C-Lesh is a game programming language for 2D games.

    C-Lesh is a game programming language for 2D games - mainly arcade and platform games. When combined with the Super Mario World (SMW) engine you can create awesome 2D platform games like Super Mario World. This language evolved from a "clone" of TI-BASIC which I began developing when I was having memory (segmentation fault) bugs with C. C-Lesh lacks memory allocation and destruction. There is no need to use pointers and you can never get memory leaks or program crashes caused by memory leaks. As C-Lesh is somewhat primitive you may like it if you are into C. I'd say its a step up from C for 2D games. Everything is set - all you need is a sprite sheet and some programming knowledge.
