I haven't enjoyed any game for long long time. All those farcry's, assassin's, all the same indie games are simply boring for me. This game however.. wow.
Devs are calling this game "Visual Novel HD", and it really is BEAUTIFUL visual novel. Love the graphics, love the animations, didn't saw better looking VN.
It is long VN. Can't say how long took me to end it first time, I guess around 25-30hours.
And every route has unique version of story, it's NOT like "choose different route, the only difference will be few graphics".
I feel like it was written by someone with real passion. I was never interested in flying, gliders etc, but while playing this game I alt-tabed many times to search for morning glory, I watched youtube videos with gliders.. Now "fly in a glider" is on my bucket list.

It's absolutely worth full price.
