I don't think you get those from young'uns, it isn't
that far away, and simply young players don't care about indie development. Except for the couple who also like making games, but those wouldn't criticize, they think everything is kewl.
It's just that i don't see the genre defining power behind an obvious limitation of older technology. (grid based movement)
It is a frequently made mistake, that these reimagining people - don't be offended - loves misinterpreting what made the original good.
However, do as you will, i only had to question it back then due to a small fear of it being uncomfortable mixed with mouse controlled functions.
As for the HUD, don't be offended, at all! But it looks very cheap. The old games here and there had some rather amusing stuff going on, but yours is some basic Photoshop crop. It should be superior to those from the past. Definitely have it redone with one of your 2d artists who make those portraits, or do some cool 3d renders for it. If i was project leader, i couldn't help myself but to add some very rarely happening animations to it, like if there was some dragon on the side it would move a bit every 10 minutes or something, that would really give it atmosphere. (works only with 3d render though... or a very hyperactive 2d artist
