I just finished Summer Pockets.
What can I say... it's definitely classic Key nakige - wheter it's good or bad thing depends on the reader's attitude. I liked it.
When it comes to "normal" routes, I liked them all. Shiroha's had some pacing issues, but other than that, I don't have many complaints. My favourite heroine from that part is Ao I think. Somebody somewhere said that she's a character taken out straight from Mashiro Iro Symphony - perhaps this impression is strengthened by the fact that she's drawn by Palette's Izumi Tsubasu - but I also had those impressions. She reminded me of Airi a bit.
Interactions with side characters (Ryouichi, Tenzen, Nomiki, Shizuku) were also fun.
True Route is split into two parts. It was highly emotional for me, even though it takes a lot from previous Key titles - there are bits of Clannad and AIR clearly visible. But I don't mind it. I really like family themes.
Art is great - it's definitely the best looking Key VN, and it just looks good on its own as well. I also loved the music - it was definitely enhancing the scenes' mood.
To sum it up - while I feel like it doesn't exactly reach the greatness of Clannad, AIR or LB, it's still prety close - very solid work. Therefore I'd rate it at 8.5/10 (the same as Kanon)
Also, while I finished the story, I might still spend some more time with it, this time having fun with mini games
