Vlambeer, the Dutch outfit that brought you Independent Games Festival award finalist Super Crate Box and Radical Fishing, has put out a neat diversion of a game called Karate, a project the developer whipped up in less than two hours to "fight [its] inner boredom."

There isn't much to do here, other than fight rapidly growing waves of dudes dropping into the game by punching them across the screen or uppercutting them into the sky (you can jump and smash the ground, too, for extra variety) -- but you don't need more than that to extract a couple minutes of fun from this.

"A tribute to what we believe karate is all about, this game is about the art of punching people into the skies," Vlambeer explains. "Karate, we assume, is all about internal strength, calmth, focus and external destruction, annihilation and bullet dodging."

"Karate is about trusting your senses, and we therefore did no research into karate and trusted our senses when creating this accurate representation of karate - or at least, in our humble opinion it is."

The developer says that it might revisit this quick project in the future to flesh it out, but it will first need to complete work on Serious Sam: The Random Encounter, the RPG its working as part of a trio of indie Serious Sam games.
