The backstory to Nanobots (select tutorial when you first play to see it) is that Groovy Greg, a hippie roboticist, has created the nanobots with the capacity to love, but they keep squabbling. Unless he can get them to work together, he'll get chucked out of grad school. His thesis advisor, Dr. Killfun, has also been working on the issue of robot love for decades and, upset by the possibility that his student will out-do him, will shortly return from his coffee break and smash the nanobots to bits, unless they can escape from Greg's tabletop.
The game's basic gimmick is that each of your nanobots has a special power (or, if you prefer, verb). That is, all of them can move and pickup, and "use" carried items on other objects in the gameworld, but each has one other function. Thus, Brainbot can "analyze" (equivalent to "look at"), Tallbot can "stretch" (to use items in high places), Chembot can "mix," and so on. From a gameplay perspective, therefore, Nanobots is a traditional point-and-click adventure game with inventory puzzles -- with the extra fillip that you need to figure out how to combine the unique capabilities of your bots to solve the puzzles.
Cute graphics, good music, amusing (though not extraordinary) dialog, and playable in a few hours -- what's not to like?
