Boondog is an action/puzzle platformer similar to classic titles such as Another World and the original Prince of Persia. The main character is quite the acrobat, able to jump, climb, and leap all over the place at will. The action is parceled out in simple moves, though, forcing you to perform your physical feats one step at a time, and only after careful thought and execution. Add to that a bit of Sokoban-style barrel pushing and you've got an excellent diversion that tests both mental and physical reflexes.
Boondog actually began as a downloadable game but managed to make a smooth transition to the browser world. Use the [arrow] keys to run left and right, and tap [X] to jump forward. The [up] arrow key allows you to leap straight in the air, grabbing any ledges your nimble fingers come in contact with. You can only reach blocks just above your head, and if you fall more than a few spaces, you'll go splat. To combat this, you're able to crouch down and lower yourself from block edges, shortening your fall. You also have the extra-useful cat grab that positions you at the ready hanging off the edge of a block. From here you can leap further than a standing jump, allowing you to cross greater distances.
Maneuvering around ledges is the key to mastering Boondog, and before long you'll be climbing, hanging, cat grabbing and dropping around each level like a pro. Each stage has an exit teleporter you're trying to reach, and making it there will involve a lot of careful climbing. You'll also need to flip the odd switch or two, often weighing them down with barrels you can push using the [X] key, to turn on platforms or switch off dangerous things.
The first dozen or so levels of Boondog ease you slowly into the game, and after that, you're on your own. Puzzles get more complex, requiring more planning and a lot better timing. Unfortunately, one mistake is all it takes to end the level, so take it slow and easy to avoid frustration. Otherwise, settle in and enjoy a great 2D puzzle platformer!
