One thing that I didn't like...
I forgot to test the demo on my old interlaced TV yesterday, but on the HDTV with prog scan enabled, it suffers from some bad texture shimmering. I never complain about visual flaws unless they bother me, but I have to say it really bothered me when I finally made it into the forest in the demo. Also when they show the bridge in the intro... argh... How come Ico didn't suffer nearly as much from this? I *really* hope they fix that for the final version. Just the fact that you can't see the ground (which is where textures suffer the most) makes the game look quite a bit better when you start climbing on the colossus.
Yeah, I'll have to test it on an old TV, just to make sure I have a backup plan if they don't sort this out. Deinterlacer usually helps with that problem a bit. Also, I found out that the game (demo) looks much nicer if you switch the TV to "warm" colors, which makes white colors look slightly warmer/reddish..
