Holdover is a puzzle platformer in the style of the old Metroid series, where you are in control of a girl named Marie who had just woken up from a deep slumber inside an abandoned research complex. A holographic image of Marie's father informs her that she was involved in an accident many years ago, and had to be kept inside a medical treatment capsule for some time so that her organs could be regenerated by scientific means. After listening to her father's advice, she sets out to explore the complex and recover her motor skills which were impaired by her long sleep in the life chamber.

The research facility is a labyrinth of corridors, platforms and underwater sections, presumably caused by flooding in the lower levels of the building. Since you can't swim nor jump very high at the start of the game, the time in which you spent underwater will be limited to how long you can hold your breath. This is indicated by the bubble shown at the top left part of the screen, and Marie will drown when this counter reaches zero. Collecting enough blue hearts, and the ability to hold her breath underwater will improve.

Players can save their progress at any time by using the quick save slot, while maps and hints in Japanese can be accessed by clicking on the capture button at the official site. To download the game, just click on the blue button at the upper right part of the web page and a link to the zip file will appear. Take note that Holdover does have some blood and nudity in it.

Frogatto is a freeware 2D platformer which stars a frog that can swallow and spit out enemies as projectiles. At the beginning of the adventure you'll discover that his reach is rather short, but the coins that you collect along the way can used to purchase upgrades that'll increase the length of his tongue.

The game features six distinct areas with thirty levels split between them, and you can use magical pedestals to teleport yourself to the start of any location that you have previously explored. You'll want to open any treasure chests that you find as well, since some of them carry life capsules or huge coin bonuses. Depending on how thorough you are when searching for secrets and hidden areas, playing the game from start to finish could take up to a couple of hours.

Kei Mesuda's Arcanacra Black Label is an update of his earlier browser-based vertical shooter release. Another Mode can now be accessed right from the start, and replays of any level by the top ranked players can be watched even if you have not attempted that particular stage yet. Bomb stock is also increased from three to five.

Click on the screen to add credits. Press the Z key to shoot and hold the shift key to target enemies with your ship's homing lasers. Switch between rapid and spread shot by holding either one or both shoot buttons. The boss of each stage can be beaten easily once your ship has a persistent lock on it, especially when the lock weapon has been upgraded.

Push the right arrow key when the main menu is displayed to view the high score table.

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. TSE-2 offers an updated real-time combat system with greater control over characters, combat speed options and action synchronisation controls to make battles more tactical and more fun.

Swarm Racer is another Ludum Dare competition entry by lexaloffle, creator of Zen Puzzle Garden and Neko Puzzle. The objective of the game is to guide a swarm of bugs to collect all gems in each level. This is achieved by using the cursor keys for directional movement and the Z or X key to change bug formation.

Get all gems before the time limit expires to progress. Certain tiles have different characteristics, all conveniently outlined with sparse but fairly complete instructions found in the main menu.

Hoshi Saga 2 is a sequel to the popular brain teaser by Yoshio Ishii, in which players have to discover the star cleverly hidden in each of the thirty-six stages by using unconventional methods.

Castle of Elite is an excellent puzzle platformer by Daniel Remar that has the distinction of using both keyboard and mouse for controls. The game eases you in slowly with easy-to-follow tutorials for the first quarter of the adventure, offering hints as needed with the press of a key.

Pick up blocks resembling Tetris shapes and place them using the mouse to create new platforms. Beat devious traps and perform death-defying jumps.

NES-related tributes and unlockables exist as well, making this a definite keeper.

Sombreros is an arcade shooter made for Arthur Lee's Action 52 remake challenge, where you play as a Mexican gunslinger who has to retrieve a couple of giant hats from the bad guys. Ammo is unlimited in the game, and you can also call upon your sombrero power to pause time and mark enemies for a round of quick fire shots. Doing this depletes your sombrero gauge, but you can replenish it by collecting hats from defeated outlaws.

You won't just be shooting at henchmen throughout the entire game. There are a number of occasions where you have to duel with one or more gunslingers, and some levels have doors that you have to break down before you can proceed. The obligatory boss fights are there as well, featuring gang leaders who can take more damage than the common criminal.

The lovable rodent from Pixeljam's original maze adventure returns for another go at navigating a dastardly tricky labyrinth in Ratmaze 2, on a quest to nibble down every single piece of cheese or edible material it could sink it's teeth into.

The first maze is made playable in this version as well, and a scroll mode can now be activated for a clearer view of the rat's surroundings. Expect to encounter puzzles such as those that requires pushing objects into certain areas or finding false walls to uncover hidden passages.

Dear Agent is a short 2D platformer with a unique concept. The objective here is to neutralize the terrorists and destroy all of their equipment before you're allowed to the next level, but players never have enough ammunition or explosives to complete their tasks. The solution here is to use the surroundings and terrain to their advantage, for example blasting away the containing area of a lava and letting the fiery liquid flow towards your enemies, hence killing them instantly and saving you from needlessly using your limited starting equipment.
