Shift 3 is a new sequel to the series of platformers created by Antony Lavelle, featuring more twisted puzzles based on the idea of shifting dimensions. Use the cursor keys to move your character, and press the space key to jump. The left shift key can be used to switch positions.

The story starts off with a feeling of familiarity but quickly turns into an open-ended adventure with multiple paths to explore. Expect to find a couple of secret passages and areas during your attempt to escape from the laboratory. You will also need to collect all four newspaper clippings to acquire the best ending.

Ikachan has been largely ignored by many due to the Japanese text, but finally a proper English version was recently released and made available for download. This translation is much better than the one that has been making it's rounds, with most of the storyline kept intact and understandable.

The game itself is a nice little underwater exploration number that won't take more than an hour or two to solve. Fans of Cave Story certainly wouldn't be disappointed with one of Pixel's earlier work.

In Excellent Bifurcation, the aliens have attacked and their ability to exist in either or both of their world and ours has given them an almost unsurpassable advantage. Take command of a special fighter craft capable of existing in both realities at once and drive them back!

The form your fighter takes on the left has double fast-firing cannons and can charge to release up to eight seekers. It is ideal for destroying small and weak but numerous enemies. The right-hand form has a single powerful cannon which fires slowly but does far more damage, and is more suited to taking out larger enemies. It can charge up to release a wave which passes through things, damaging them as it goes. You can switch them between the worlds depending on what kind of firepower you need where.

The only vulnerable parts of your ship are the white parts at the centre. This means that the small form is much better at dodging than the large one. The only dangerous parts of bullets are the brightest (yellow or white) parts. Also, if you are shot down the form which was hit emits a green shockwave instead of a yellow one.

Press the Z key to shoot, X key to charge the special weapon, and C key to switch between two forms. Use the A key to activate autofire. You can change settings, like windowed vs fullscreen and whether it uses vsync, by editing the init.txt file.

Space Phallus is a retro horizontal shooter with a naughty theme, created by the author of Bullet Candy. Here you pilot the disembodied head of a dog, fighting against hordes of enemies in the shape of unmentionable body parts with only an assortment of three weapons at your disposal. Thankfully these weapons can blow away anything that stands in your path, just as long as you use them wisely and sparingly.

There are three stages to play in total, with levels two and three accessible by pressing the 2 or 3 key on your keyboard when the main menu is shown. The game features an online high score table, a special guest appearance by General Custer himself, and is available for Windows, Mac OS X and Linux operating systems.

The Black Heart is a versus fighting game which took Argentine developer Andrés Borghi seven years to create using Elecbyte's M.U.G.E.N. engine. There are six playable characters to choose from, each with their own set of special moves that can be executed using simple key press combinations. In addition to the basic attacks, players can also charge up their energy gauge and perform a powerful fatal move to finish a duel in style.

The game also features a couple of gameplay modes separate from the main story campaign, with support for hotseat multiplayer also included.

Photopia is a piece of literature by Adam Cadre rendered in the form of interactive fiction, and written in Inform. It is regarded as a pioneer in narrative-driven, rather than puzzle- or challenge-driven, interactive fiction, and is perhaps the most successful example of this genre to date. It won first place in the 1998 Interactive Fiction Competition.

Photopia has few puzzles and a linear structure, allowing the player no way to alter the eventual conclusion but maintaining the illusion of non-linearity. This gives weight to some of the story's motifs - questions of free will and determinism.

In Sumotori Dreams, each bout starts when both players touch the ground with their hands and ends when a player falls to the ground or steps outside the circle. A cube of the winner's color is then thrown in to signal the end of a round.

To win a game you need to have two points more than your opponent, and a total of at least five. Use the enter or backspace key to push, or press the arrow keys to move your character around the circle and change the camera angle view. Hold the down arrow key to touch the ground. A hidden mode can be unlocked during the main menu display by breaking one of the walls on the far right.

5 Differences is a spot the difference game in which pictures come alive with all sorts of animation and movement to confuse players. It is actually possible to solve most puzzles by crossing your eyes and concentrating on the image in the middle, then clicking on objects which are either flickering or flashing.

Goo is a soft body fluid physics game which can only be played using an Xbox360 wired controller. The goal of Goo is to surround enemy goos using your goos. When you surround a piece of enemy goo, you'll assimilate its mass and earn points. Like oil and water, goos don't mix, but they can be pulled and pushed around to surround or cut through each other.

You control a goo via the cursor called a Pilot. This Pilot can move around in 2D by using the left or right analogue stick. Moving the pilot around the Goo slightly perturbs the liquid near it. By pressing the right or left trigger, your Pilot will suck nearby goo, creating a dense patch of goo.

Death Worm is an action game by JTR in which you assume the role of a large creature with an appetite to match it's size. Hold the up arrow key to accelerate, and use the left and right arrow keys to change directions.

Vehicles can be launch into the air when approached at the right angle. Consume food to increase health.
