All is looking good so far, finished the first ages, got the cleft book, relto pages and most of the sparklies. I only found one glitch so far: in Teledahn I got into a climbing-down-the-ladder-loop. (much like I've experienced in Moula before.) It was the ladder below the starting point. It's easy to jump out of the loop, so I'm not really troubled by this.
I noticed that walking up and down stairs is going faster than in Moula or the other shards. Although I believe that's great when you have to climb the great stairs for example, it is not looking natural. That's because the avatar is now running slower over horizontal ground than it is in running up the stairs. It is more noticable when the stairs has only few steps.
But I have to admit, every time I do Ahnonay, I find myself wishing for a boost or turbo button for my avatar...
