First "usability test" with N900 and one hand (while walking, to make it more X-treme) was not very satisfactory.

Fast moves where not selected or completed and I had to mover again, slower. Can this also be related to the "heavy" feel reported in the previous post?

A couple of wrong destination squares. Not bad in terms of percentage of moves but you just need one miss to loose the game...

But nothing that feels like a showstopper for a unstable release. I will keep playing.
