Here's one: Indie Game Critique.
I just wonder how some indie games (including, but not limited to: super meat boy, cave sory, Redder(lovely), hydorah, luynne dyversity, Coal, The life of a pacifist is often wrought with conflict, Blackfoot, Tormshire(wip), Gungirl 2, Hot Ninja Moon Moon, Dust an elysian Tale, Runman Race around the world, desktop dungeons, loved, Fleet assualt, Generic, Rocket ninja cyborg, Level Up, etc, etc, etc) would be critiqued on here. I mean, some of them are obviously not pixel art but some of them are. I just wonder how these and many other games would look under edits and what critique would be given to them to improve on there art. Just a thought.
