Build your own fully functional robots and use them to slide, crawl, roll and fly your way through a large interconnected puzzle-world. Collect components such as wheels and rockets. Re-wire controls and change the configuration at any time during play to solve the puzzles at hand. Infiltrate the factories of the Mobiloid Corporation. Level design is Metroid-inspired, ie. folded on itself and progress made by exploration and power-up.
Man, i love so much games like this where you are trying to find more pieces to put on your quadra-wheeled-jumping-copter :)
10/10 for me for the sheer awesomeness of this
