After rating 100 games, here are my favorites so far. No particular order here.

Proletarian Ninja X
A highly polished stealth game where you play as a ninja who has 10 seconds to assassinate all of the capitalists in a given room. This game features an intuitive point-and-click control scheme and frantic sneaking action.

Lean Mikey’s Mega Muscles with Lean Mikey
A wacky button masher where you play as an ambiguous creature tasked with 10 second workouts and impressing ladies. This game has charming atari-style graphics and an interesting rpg-like stat management mechanic. This is probably the most humorously entertaining game I’ve played so far.

Hallucivian
A trippy action game where you are a bird who has 10 seconds to place an egg in a safe spot so it can hatch. The atmosphere here is well done, with a tight cohesiveness between colorful graphics, sound effects, and music. The physics involved with the bird and eggs provide a pleasant challenge.

The Unbelievable Adventures of Kamil the Cat
An adorable and humorous 10-second minigame collection where you help Kamil the Cat through an adventurous morning. This game has a nice variety of minigame mechanics and an entertaining storyline.

MegaPunch
A online multiplayer beat-em-up where the platforms change every 10 seconds. It’s very impressive for a 72 hour Jam entry. The fighting is frantic and quick, with each successful hit, rock, or bomb throw killing an opponent. The music is also blends with the beautifully retro environment well, and both provide a pleasant contrast to the murderous action. This is one game I really hope gets expanded on after the competition ends.

SuperSleepTime
A beat-em-up where you are a hero who slept in late, and has 10 seconds to find & equip as much of your gear as possible. The items you find have an effect on the gameplay once you hit the streets to beat up some thugs.

My Tenth Adventure
A point-and-click game where you have been tasked with a bizarre, enigmatic adventure. A mobile phone provides the means to add 10 seconds to the time limit for each scenario. This entry is quite artistic. Fans of Fez and Superbrothers: Sword and Sworcery will take delight at the inspiration that this game draws from them.

Dark Interval
A side-scrolling horror/thriller game where you are a man trying to escape an evil entity. This game does an excellent job of invoking a feeling of suspense and horror. You frantically search for the means to exit each room as the monster begins to force its way into your room after 10 seconds.

Scraith
Another horror/suspense game, where you are trying to avoid evil creatures while collecting orbs. You are able to move for 10 seconds, and then you’re frozen as a creature has it’s own 10 seconds to approach you. Very creepy and chilling game, especially as you are forced to helplessly watch the creature approach you. The unsettling combination of a 3d environment with 2d graphics adds to the experience.

Holiday In Russia
This insane top-down shooter drops you into a field filled where you must fight for survival against waves of bizarre creatures. Every 10 seconds you have an opportunity to enter a shop where you upgrade your equipment and restore health.
