When you save a level with too many objects, your level will fail to load because it has become corrupt. When you build contraptions, there's the 120-piece limit that prevents this (most of the time) but the level editor doesn't have an equivalent. This tool will attempt to salvage your design and give you the FCML version of it so that you can salvage your work.
Fantastic Contraption is a fun, free, physics game that encourages players from any age (young to old) to create contraptions from a wide variety of parts such as motors (powered wheels), plain old wheels, and two kinds of rods to joint together different parts. The physics simulation game is web-based and only requires Adobe Flash player to run. So, for all those who want to take a break away from first person shooters (FPS), roleplaying games (RPG), and strategy/RTS games, Fantastic Contraption is a great game to try out. Fantastic Contraption Resource is a fan-created resource website for Fantastic Contraption that provides many functions that the game currently lacks.
