The rules of Coolio Niato's browser game light-Bot are simple: guide the little robot across the factory floor and onto the blue squares, and then light them up.
To control the robot, you arrange commands into his method slots, and watch him go to work. Space is very limited – for most puzzles, you'll need to establish re-usable functions: a single command that consists of multiple moves.
That of course is where things get tricky. Prepare to spend a bit of time cleaning up your code, as visualizing the path the robot will take is a lot easier than actually getting him there without using up your alloted method-space. Fortunately there's no time limit – instead, try to complete each puzzle using the fewest commands possible.
There are 12 puzzles in all, with the standard Kongregate badges and points for various achievements. As an added (though unlisted) bonus, the best robot programmers will (presumably) be given short, merciful executions when Skynet finally becomes self-aware.
