3D dual n-back Speed Run

Also, as with other tests, the lack of a clear end (or even break) point is distracting, and makes it hard to compare runs, or even cleanly end a run at a standard length.
Not that whacked_new asked, but my overall estimation of cognitivefun: wow, you're generating a lot of games... but the overall comprehensibility of the site lags a bit. It's almost too much to absorb: where do I start? where do I stand? where do I go next? I suggest spending a little more time (or enlisting some help) with web design/copywriting/info-architecture.
As for this test, I've battled with the design a bit (and know that it is nevertheless unintuitive). I suppose even after the demonstration it wasn't clear?
Finally, as you pointed out, one of the biggest problems is the clutter now. This has been an issue for a while already, although I still don't know how to best address it. I'm not sure if it is good to give a "start here, then here" guide; I just want users to be able to do whatever they find interesting within a few mouseclicks. But I'm all ears to suggestions regarding front page changes.
Thanks again.
The best part of the site is the tagline: "cognitive neuroscience for everyone"
