Robin Vertical Venture

Robin Vertical Venture is a Teen Titans game featuring Robin who's climbing up the artificial wall full of all kinds of obstacles. The idea is to get to the top in less than a minute and earn a merit badge in Gravity Defiance. Controls are basic and all you need to use are arrow keys. Avoid laser beams, falling rocks, water splashes, big mechanic punching hands. You can always hide in a wall's whole, but keep in mind that should be just temporarily, until the danger's gone since in this game you race against the clock and there's no time for resting.
The game has been inspired by the the Teen Titans, an American cartoon TV series which is based on DC Comics characters. Robin is known as the Batman's sidekick who at some point decided to stop working for Batman and became the leader of a five members crew later known as Teen Titans. Just like in this game, he always appears in green tights, wears a black and white face mask and a big 'R' letter across the red vest.
Other games where Robin appears are Batarang Challenge and Batman in Crime Wave
