In Shift 4 you're in control of an astronaut whose ship was attacked by a giant squid, forcing our protagonist to make an emergency landing at the closest planet. Waking up to find your family members missing, you decide to explore a deserted facility nearby and search for clues about their current whereabouts.

This particular episode is a little more challenging than previous releases, since players are required to switch between two or more characters often to solve some of the harder puzzles. New gameplay elements such as gravity and contact-sensitive switches are introduced at a steady pace, which is a boon considering that the map is a lot less linear and there is a bit of backtracking to do as well.

Nezumi man (Rat man) is a 2D platformer created in the same style as early Megaman games, where you are in control of a rodent who has to defeat the evil Dr. Gyoniku and his henchmen. Ratman can jump, shoot, slide, and earn special abilities by beating the boss characters in each of the eight levels included.

A hidden bonus chapter can also be unlocked once you've completed the entire game, although it doesn't really take more than two hours to achieve that feat if you're already accustomed to playing difficult platformers by now. The save feature will come in handy if you need a short break or two between sessions as well. You can resize the application window by using the configuration file included in the game folder.

The Spirit Engine 2 is the follow up to the freeware game The Spirit Engine, first released in November 2003. Set in a new world, with new characters, new graphics and a rewritten game engine, TSE-2 improves upon the game experience of the original in every possible way.

The story is about three citizens who discovered their paths crossing in an act of charity one dark night, finding themselves burdened with the responsibilty of not only defending the nation but deciding whether to save civilization as they know it.

Invisible Vision is a 3D arena shooter set at sea, where players get to engage in naval battles with enemy submarines while surviving the occasional boss encounter or two. Wireframes are used to replicate the surroundings of a dark ocean, and with careful observation you can easily detect enemy ships based on the ripples caused by their movements.

The arrow keys can be used to move your ship around. To launch a torpedo, just press the Z key. Every missed shot costs three seconds, and the game is over when you run out of time or lives.

Think Under Defeat, but with 2D sprites. Demolition Gunner: In Search and Destroy was originally developed for a three minute gameplay competition, then turned into a complete production featuring seven stages and obligatory boss encounters.

These battles last only twenty seconds each, so there won't be much of a struggle beating them assuming that you're good at dodging an insane number of bullets. Press the Z key to shoot, or hold the X key for a few seconds before releasing the button to launch a napalm bomb. Click on the first link after the title to download.

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.

Use the Z key to shoot, hold the X key to take cover, press the C key to lob a grenade. Bonus points are awarded for efficiency and combo length.

An automatic online high score submission feature is included.
