I cast my vote for "I feel that something was missing". Just finished it one 4 hour play session and well, its a good game, but not what I was hoping for. Shays part of the adventure more or less just annoyed me. The overprotective mother computer was bearable, but it really annoyed me having to play along with the wolf guys wishes. It was so obvious that he was up to no good that I really tried everything not to just do what he asked me to. Of course there is no other ways to complete the game... :-/ Vellas story I did enjoy a lot more.
I'd says the puzzles were much to easy. I just breezed through the game with little to no thinking required. Granted it took me 4 hours to complete, but thats because I explored everything as thoroughly as possible. Looking at the steam page the classification as a "casual" game is fitting.
The story is pretty good, but rather tame, no edges, just what a big publisher would like from a game. I had hoped Tim would use his new freedom but I guess you forget how to fly if you are used to a cage for so long. I have to commend the voice acting though. I found they did a really great job bringing the characters to live and helped selling the story a lot.
Graphics wise I was mostly impressed with the look of the game, but I did encounter quite a few graphic glitches that I didn't expect in a release that was called "polished". Also some of the close ups of the backgrounds should have been redrawn and not just zoomed into the original digital painting. Granted, it works most of the times, but there were some really ugly close ups that spoiled the otherwise beautiful art.
Overall I have to say I had a pretty good time with Act 1, but so far its no candidate to become a classic.
