Look! Over there! It's a giant robot alligator with a bunch of little drills going out to get some sushi! Before he sees us, reload your grenade gun with cherries and tap the appropriate key when his sushi order floats over the red zone!
Avert Fate (Mac/Windows, 90MB, free) - Gritty first person shooter designed to show off the capabilities of the Unity engine. For the most part the gameplay is standard FPS fare, but there are some interesting weapons to mess with, and fighting alien ships in the sky is always a plus. Hit detection feels a bit rough around the edges, but you'll forgive any sort of awkwardness when that huge robot steps into your view.
Alex the Allegator 4 (Mac/Windows, 1MB, free) - Platforming pulled back to its basics, even the color palette emulates the green hues of the original Game Boy! This installment is part of a series of wildly different games that includes a puzzle title, racing game, and multiplayer platformer, although I enjoyed Alex's run and jump antics a bit more than the other games.
Little Machines Still Goes Deeper (Windows, 7MB, free) - A cute, colorful arcade-style "digging" game where you must control drills burrowing under the soil to collect gems. Click and drag the mouse over a drill to select a direction, but avoid rocks of any kind, as they'll destroy your little machines. Fun time waster, especially when things get more hectic and you have to choose between collecting gems and keeping your drills safe.
Waxy's Sushi Party (Windows, 12MB, free) - An intense Game Maker-created game of reflexes that marries Dance Dance Revolution-style button tapping to a resource management sim. Sushi orders, represented by colored dots, pass by the red and green areas at the bottom of the screen. Use the keyboard to "activate" the areas while an order is on top to fill it. Keep an eye on the bills section to the right and use the numpad to add up completed orders and charge customers what they owe. Things get frantic pretty fast, but when you get into the swing of things, there's an almost Zen-like beauty to playing. (Note: Game is "Play Now" only, meaning you must install an Internet Explorer or Firefox plugin to play.)
