Doors: Out of Office is a puzzle platformer by Arctic Arcade, where every threshold promises to turn reality upside-down. Help Dave get out of his office's forbidden door of mystery and home for a well-earned weekend. While it could use a better sense of perspective, the game has intelligence and quirkiness to spare.

Tick tock on the clock, but the party won't stop, because Ozzie Mercado has just released Twelve O, another wonderful, simple idea puzzle game! Thinking rotationally can be mind twisting, and while the mouse controls can take a little getting used to, Twelve O makes for a great time-waster.

Topsy Turvy is a game in the proud, recent tradition of platformers with a twist. Like others in the genre, Topsy Turvy is focused around simple, familiar mechanics like move left, right, and jump, avoid enemies and spikes, and get to the goal at the end. We all know how to play that game, right? Well, Topsy Turvy says, now gravity is relative. Chew on that.

Bipole is a physics-heavy spin-cycle of a puzzler. The goal is simple: annihilate all the cute, smiling particles by colliding them with particles of the opposite charge, taking advantage of gravity and electrostatic attraction/repulsion to gain momentum.

Andrew the Droid is a retro-looking title that utilizes the familiar level rotation concept found in a number of games. Work your way through over two dozen levels, avoiding hazards as you unlock exits, collect chips to grant you new abilities, and rotate the stage to let gravity pull you where you need to go.

Is anyone tired of Portal-inspired games about some faceless dude stuck in a sterile laboratory environment full of death traps yet? I know I'm not! Here's another one, comin' atcha! Control a smoothly animated silhouette of a man who is trapped in the middle of a giant maze full of spikes and shifting blocks. Alter gravity by rotating the entire room 90 degrees at a time!

Sola Rola is a topsy-turvy turntable of a time, published by Gimme5Games. Wiz and Waz are two spherical buddies who are just cruising through space one day and happen to get caught in a series of mazes, a scenario we can all relate to. Together they must escape, but they only move when you rotate the maze. It's your job to roll them right into the red and blue beacons that represent their exits.

In Spin the Black Circle you must rotate the game field to move a ball to the goal in each stage. Gravity pulls it to the center, however, making physics and fast reflexes vitally important to your success. Avoid obstacles and enemies in this well-polished game of skill!

Mindscape is a side-scrolling platformer with a... twist, in that the entire level rotates as you play. There are three "worlds" with four levels each, which steadily progress from the creepily joyous Candy Meadows to the joyously creepy Center of Your Mind. It's a brilliantly conceived and executed platformer of the highest level.

The enviably talented crew at Nitrome have just released their latest game and it's an ambitious effort to put it mildly. Roly Poly is a Flash action game of skill with a unique mechanic: Click and drag to tilt the play field and use gravity to roll the little hedgehog to the goal of each level, and within the time limit provided.
