What would you go through for a ton of carrots? Probably not a lot, but Jack Tube, the armless white rabbit from the Begamer game of the same name, would gladly traverse 13 levels of puzzle platforming madness... with the help of your clicking finger, of course. To finish each level, he has to collect all the yellow gems and then hop into the rocket, using the environment to his advantage to get some of the harder-to-reach items.
Everything is mouse-controlled: click ledges to jump up to or down from them, click enemies to attack or jump over them, click tubes to hop into them, and so on. The pictures drawn on some of the walls help to illustrate some of the more obtuse concepts (for instance, you Portal fans can probably guess what happens if you jump into a tube from high up). Although the control scheme and some of the gimmicks in later levels make it clear that Begamer isn't doing a perfect job of disguising its usual point-and-clickery, and it's not exactly a difficult game, this is definitely a clever and interesting departure from the formula... and if that doesn't grip you, the charming visuals and audio most likely will.
