Are you ready for a point-and-click adventure that's totally algebraic? If you're wondering what algebra has to do with anything, clearly you're unfamiliar with the hit Cartoon Network series Adventure Time. The show features plucky protagonists Jake (the dog) and Finn (the human), the surreal, magical, post-apocalyptic Land of Ooo in which they live, and (most importantly for this game) recurrent villain the Ice King. The Ice King kind of has an obsession with marrying a princess. Any princess. Any at all. So he freezes Hot Dog Princess, Slime Princess, and Princess Bubblegum, and it's up to Finn and Jake (and your cursor) to rescue them in Legends of Ooo. Mathematical!
Point around with your mouse. If you hover over something you can pick up, the cursor will become a hand. If it's something you can look at, your cursor will become a magnifying glass. If it's someone you can talk to, it'll be a speech bubble. And lastly, exits turn your cursor into a door. You have to actually drag items from your inventory where you want to use them, and there's no item combining. This is a pretty simple game aimed at children, so you have an in-game hint system and you can pick up more hints by getting snails. The in-game hints are implemented very well, actually: they start out subtle and then get more explicit, so if you just want a nudge, they're great for that.
While the game may be geared towards kids, it was adults who made the original short a viral hit and who drive much of the fanbase even now, and they won't be disappointed by this game, which features a lot of sly humor that will go over children's heads, without compromising the appropriateness level. It's surprisingly long, too, so when you consider that the episodes of the real show are only about eleven minutes, this is like a bonus episode. The game doesn't require any knowledge of the show to complete, since the character's dialogue provides all the clues. Adventure Time fans shouldn't miss this one, and non-fans might become fans by the end of it.
