They're walking a fine line between keeping it classic, and modernizing. I think the textures look absolutely perfect. Maybe they could increase the resolution, but if you're looking for them to change the aesthetic, I REALLY REALLY hope they don't AT ALL.
No, I'm with you, the aesthetic looks good...just the texture quality is SO low for most of the environment, it's extremely noticeable. If they clean that up significantly I'll be happy. I just can't tell if they are doing it on purpose or if it's just because it's pre-alpha.
It's been a bit slower than I would like considering I'd really like to see most of those stretch goals reached.
