So this game doesn't really have that much H in it, relative to its total play time. I recorded all 11 CGs and in game animations, and the total run time (after some minor editing) comes out at a whopping...12 minutes. Mind you, I even let the CGs loop three times each for the video. For about 6 hours average spent on a blind play through, you don't get much banging for your time. I do realize how much work is put into animating this. Although the CGs are all excellently animated, as to be expected from Libra Heart, they all kinda lack sound effects? I mean, you can hear the character's voices, but not any sounds that you'd expect to hear from the actions on screen.
The CGs are not well paced either. You can get 8 CGs by the third dungeon in the game, about one or two hours in. But the 9th and 10th CGs are located in the mid game (the Ice Cave and the Desert, respectively), and the last CG is in the final dungeon. I expected to see new "hearts" enemies every time I enter a new dungeon, but nope, it's the same tentacle or zombie boi again (or both).
So for the verdict, if you're playing solely for the CGs, just look up a gallery video online my guy/girl. You can download a complete save file, but the in game gallery kinda sucks. There is no sound/voice, and you can't control the action either. It's just like watching an automated .gif slideshow.
The gameplay itself is pretty decent, but exploration can be such an ass. The game lets you progress without crucial items, so you could end up getting stuck in a pit without having the wall climb ability yet. Thank goodness for the scroll of return. I somehow got all the way to the Ice Caves without having double jump before realizing something is wrong lol.
