Not bad. OK.
Hmm..pretty good but you could do a bit more
This game is incredibly beautiful, if simple. But what is lost is the point being made. The game is too slow and the reader is well, not that slow a reader. The validity of the point is lost in the impatience to see it. While the intent may have been artistic and gentle, the result requires more patience than such a simple game needs for the average gamer. There's lag, which increases the very slow speed of the game.
While I found this game very beautiful, I think it tried too hard at being artistic and the speed was one of these things. That being said, I think this is an amazing work for a first go and look forward to more from you.
Normally I like these, but I've seen this exact same concept before. (Google "Inside a Dead Skyscraper game" to find it). Once that novelty was over, the game wasn't that interesting aside from finding all the pieces. I wish you had more locations with meaning to visit, because that was the coolest and most touching part of the whole game to me. I feel like the previous game I mentioned had more impact on me, however, but it was shorter. (The feeling of WEE flight! was more well done in it as well.)
I also felt the ending was too long-winded. It was nice poetry, but I wish I could just use spacebar to read through it. I can read faster than that, and I know that at some parts you had to time it with the video, but other times it would've worked fine. I actually found myself browsing through other tabs waiting for a line to fade away.
Overall if you'd have fleshed this out more and made it more gratifying to fly/more things to discover (exploration was not rewarded, in fact the slow flight time made it a pain) I'd have not cared that this concept was done before. However, it wasn't really improved enough for me to think this above average. I'm sorry. =(
Although, I encourage you to do more stuff, because this was still a good distraction, it just needed more to it. =)
I'm not sure what exactly is going on here, but what ever the hell it is good.
