I absolutely love independent games and this year's crop of IGF 2011 entrants and finalists just may be the most creative to date. From the super-popular and amazingly successful Minecraft or Super Meat Boy, innovative gems such as Desktop Dungeons, Amnesia: The Dark Descent and more, there's something for every taste (as well as plenty of games a non-gamer would try). A few of the nicer surprises have been the as yet unfinished projects that show off some amazing innovation in visuals as well as gameplay.
For me, the best example of this is the beta demo of Tiny and Big in: Up That Mountain, developer Black Pants Game Studio's wonderfully fresh and funny episodic 3D adventure/platformer (for PC, Mac and Linux) that features stunning comic-styled visuals and excellently implemented game mechanics that are simple to understand while allowing for a number of ways to tackle environment navigation. The current demo build is a bit raw and definitely needs more work, but what's here will make you crack a smile that lasts for as long as you're playing.
