It's only around 6 hours according to vndb. Sure, I got time to waste. It's to make it up to Key for me never finishing Clannad, Rewrite, and Little Busters. I really like Mochizuki Kei's art too.
Kinetic Novels are just anime movies without enough budget for making some proper animation so instead they just show you a few frames they actually had the budget for.
Yeah, pretty mid. The story wasn't bad but this isn't really a game, more just a 6 hour - ish story. If you got half a day to kill, go ahead and get this. You could do worst.
In other words: As games, they are shit.
