Noted Japanese indie game developer Kenta Cho (Tumiki Fighters, Blast Works) has a new browser-based game called Sin Car, an arcade racer in which you control a fluorescent car that moves side-to-side in a sine wave pattern that you can adjust.

By increasing or decreasing the frequency (which also affects your car's speed), you'll be able to pick up collectibles and avoid hitting the walls. And that's it! There isn't anything more to Sin Car, but its simplicity and leaderboards make for an addictive game.
