Stomped.io

Stomped.io is a game where players stomp each other by jumping on their heads.

Gameplay
The point of the game is to jump on other players from above, using the arrow keys and the space bar (alternatively, the mouse may be used). Other players will attempt to stop your character, so good reaction times are needed. Use the platforms scattered around the map to gain an advantage over others. The character will slowly grow as experience and stomps are gained. As they gain experience, the player's name will appear on the leaderboard and will eventually rise to the top if played long enough.

Skins
The first 7 skins are available by default. The rest must be shared on Facebook or Twitter to unlock.
