I finished Wind -A Breath of Heart- . Have to agree with @Decay, this VN has some serious pacing issues. Common route drags on and on, and then heroines' routes feel really rushed. However, the story wasn't bad - especially sisters' (Nozomi and Wakaba) and true (Hikari's) route. But a word of warning - while on the first glance it looks like moege, this VN's specialty are bittersweet endings. It's a nakige mixed with mystery. On the romance side - it feels a bit lacking,
