What can you say that hasn't already been said about Flappy Bird? Same graphics (nice color scheme though), same sound effects (nice music though), and the same gameplay. I was a little annoyed by the fact that the bird moves so slowly in this version, but considering it doesn't really matter how far you get I wasn't really frustrated.
What did frustrate me was that the game hiccuped like crazy. From the moment I started the game, the music frequently cut out for split seconds, and it was common for my spacebar to decide not to work while playing. I don't know if this is made in HTML5 or Unity or what, but you probably could have made this exact same game in Flash 5 and it would have been more stable.
That said, the dialogue was decent, well-written, and poetic. What I found odd about it was that you used Flappy Bird as a medium to express the text. I get that there's this whole "jumping through hoops" thing but honestly the hype surrounding Flappy Bird made it very hard to take this seriously. One of the things that made Flappy Bird viral was how STUPID the game was, in a funny sort of way. That doesn't translate well into the existential depression expressed in this game. This doesn't catch me in the gut the way Billy Suicide did, or provide original gameplay like Fixation did - it just presented a sub-par game with a message that tried to fit in and didn't. The result is that the two clash pretty badly. Oh well, if nothing else it's kind of funny.
