Doeo

If you have not yet contracted carpal tunnel, and would like to get it, Doeo(s) is the flash game for you. You have 40 seconds to gather 100 Doeos!

Doeo is an incredibly addictive and ridiculously intuitive flash game by Raitendo. I'm not entirely sure what Doeo means, although it probably has something to do with unibrow. Or ear-less square rabbit-face. Or compressive neuropathy. I dunno, definitely one of those three.

The game takes a little while to load, then it lets you choose game subtitles in English, Japanese, Swedish, or Crop Circle. You will then immediately feel like you're trapped inside a Japanese game show, whose catchy soundtrack was written by an addict hopped up on amphetamines. Just start clicking away at the Doeos like they were those whack-a-moles from your childhood.

You progress by memorizing where the most Doeos will show up, and by keeping your mouse still while clicking the quick cascading processions. For an extra challenge, click "hard" or try to play Doeo with a track pad. I dare you! Enjoy!
