Tommy Tuovinen's Lime Rick is one of those great little puzzle games that takes you by surprise with its simplicity. Using [WASD] or the [arrow] keys, guide your stone-faced little green avatar to the delicious red apple in each level. The catch? You can't jump or get over obstacles higher than one square, and if there's nothing to support you, you'll fall straight down. As you go, however, you extrude (ew) segments of your body behind you that you can stand on, enabling you to plan your path in a way that uses your own body in a gradually growing series of platforms to navigate the level and meet your goal. You can hit [R] to reload if you get stuck since you can't double-back on yourself and you can only go straight up for so many moves, or just [Z] to undo as many previous moves as you like.
With 38 levels, you may expect Lime Rick's concept to get old far before the game is over, but for those of us who enjoy a clever yet uncluttered mechanic and the simple pleasure of logical planning, this is a rare treat. It's not a game you can just bulldoze through, especially given how big a part planning a course will mean in winning most stages. Once the game start throwing in simple little twists that add to the difficulty like blocks you can push, you'll realise this is definitely not going to be as easy as it looks. It doesn't have a lot of bells and whistles, but then, Lime Rick is proof that you don't need any if you've got the brains to back it up.
