This is one of those games that you probably pulled out back when Steam used to do their sales events. Then you put it back away for a very long time. I don't blame you. It's fun for about 15 minutes, but then you just keep doing the same thing over and over again. There's only so much fun you can have in a game about jumping off buildings. Well....maybe that's not true, but there's only so much fun you can have in this game.
You start each round by jumping off a building. Points are scored for getting close to objects without hitting them, interacting with people (thumbs up or flipping off), flying through certain gates, and sticking your landing. This gameplay can only interest you for so long. The controls work well enough while falling, except controlling after deploying your parachute can be a little awkward.
The visuals are bright and intense, but not all that interesting. There are lots of flashing lights which could be problematic to some people. The music is fast and somewhat entertaining. Maybe the best part of the game.
I could not recommend this game for more than a few minutes playtime. Fire it up if you got it in a bundle, but you will quickly put it back away.
