Megazeux (MZX), the popular game creation system based on the Tim Sweeney’s legendary ZZT, has been ported to the Nintendo DS by MZX developer and homebrew hacker Kevin Vance.
I had a good time playing with Megazeux as a kid! The simplicity of the engine is great, and it only takes a few hours to make something fun. Some of the classic MZX games (like Bernard the Bard, pictured above) are extremely clever. Good to see it on the DS!
Download MZX for the PC here (Sourceforge), and try the games at DigitalMZX (MZX is required to play).
