The Ingenious Machine: New and Improved Edition

The Ingenious Machine is a single-player, physics-driven puzzle game. The player is presented with a series of light bulbs, and occasionally some obstacles. The goal of each level is to switch on the light bulbs by creating an elaborate machine out of a pre-defined array of gadgets. For each level, points are awarded for creativity - The more elaborate your machine, the higher your score. However, your score is halved with each failed attempt at constructing a working machine, making this game the ultimate trade-off between creativity and practicality.
