Sky Serpents, from popular developer Nitrome, casts you as a quasi-Norse hero on a sky-borne, gravity-defying quest to kill as many sky-serpents as you ca to beat all records. Credits:Sky Serpents is developed by nitrome. How to Play: How to Play:Control the little sky-Viking upstart with the [arrow] keys. Slash your sword with the [spacebar]. Key to successful sky-serpent-slaying is latching onto vulnerable spots and other areas, using the [arrow] keys in the direction you need to stab. That way you can hold on while your prey bucks and weaves and slithers about. You don’t need to continue holding the [arrow] key to stay latched on, and you can detach yourself by using the [arrow] keys in the opposite direction. By sufficiently crushing every vulnerable spot, you defeat your snaky quarry and move onto the next level.
