Agreed. It seems the artist changed for that game or the old one changed his artstyle drastically.
All in all the art in the first game looked more juicy in the details imo.
Edit: Yeah the artist changed. I mean the CGs are not bad but the first one was better.
That's really lame though. The main draw of games from the same circle is generally the artwork/style.
If that can't even be kept mostly consistent, then there is, in the same sense, generally little reason to go for a game based off older work. Especially in these types of games where gameplay is an afterthought.
Haven't played this one yet (just the first one a while back), but just comparing screencaps of both, I must agree with the statements here. Artwork in the first game was better.
CG's were more vibrant, closer to VN level CG, compared to this one.
