Imagine Shadow of the Colossus was a little bit more rubbish, didn't have an awesome tear jerking story, featured weird looking snakes, and was set in the fricking sky. Imagine all of that stuff shoe horned into the flash, 90s Square-Enix aesthetic and you should have, fixed in your imaginations, something a little bit like Sky Serpents.
Sky Serpents is a game in which you slash Sky Serpents to death. With a giant sword. In the sky. It's as simple as that. It does a great job of representing feedback in the game, which makes the whole slashing Sky Serpents thing a lot of fun.
Give it a bash.
