3D games? 2D games? Can't we all just be games and get along and have happy times together? What? Nobody's debating this and there's no contention in the gaming community over the game types? Then, why am I still writing interrogative sentences?!
Beret (Mac/Win/Linux, ~40MB, free) - The 2D puzzle platform will never die, and Beret, despite its amateurish visual exterior, is another reason the genre should continue to thrive. Playing as a scientist who has gained telekinetic powers, you decide your employer, Evil Corporation, is too evil for your liking and decide to overthrow it and punish the wrongdoers. You do this with a smattering of telekinetic abilities that allows you to pick up and arrange blocks with the mouse, constructing platforms and re-building bridges as you move across the stage. Lots of levels to play, loads of collectible items, and a level editor you can unlock make this one well-stocked indie game!
Mythology (Windows, 19.8MB, free) - A 3D action adventure game not unlike the later Legend of Zelda titles. You play as Timaeus who is searching for his parents who were lost at sea. You start off on a rather stiff dolphin-assisted escape from a hydra and end up running around ancient Greece with a sword and shield. NPCs to interact with, treasure chests to find, quests to fulfill, and items to find, this lovable game has got everything you would expect! Mythology may be a bit rough around the edges, but the gameplay is enjoyable in an old school sort of way.
One and Light (Windows, 7.3MB, free) - A short, unpolished 3D platform game created in three days for a contest themed "shrinking". This curious little game gives you the ability to grow and shrink with the press of a button (er, two buttons, but you get the picture). Size yourself down to make tiny areas appropriately explorable, then get big again to traverse difficult landscapes. Quite a confusing experience at first, but once you get the hang of it, you'll see how interesting on-the-fly size changing can be!
