The H content outside of the player character is weird in this one. The enemies that can do it are very specific ones with hearts floating around them in each stage, which you need to touch with your crosshairs but not kill to get to do their thing. So they're kinda doing it like the last game where you need to hunt them down in-stage and grind off them sort of to build up your character's lewdness level for the inn scenes.
Unlike their last game it doesn't seem like there's a gallery area however, meaning if you wanna view those H-scenes again however, better remember the location in the stages for the ones you really like and hoof your ass back there to view it again. And you can only repeat this as many times as you can tolerate screen transitions, and the girl's health holds out, before you need to leave the level and come back. At least the enemy kill barriers seem to stay down on return trips. Sometimes. I've had one show up again at least once, possibly because I died in the stage. So who knows if them staying gone is intended or not.
Building hit combo seems to be a huge key part of this game as well. It does a bunch of things ever 10 hits it seems. It increases your super meter faster, can trigger item spawns, and seems to have a low chance to refill some of your girl of choice's health as well. Some enemy types make it really damn annoying to build this up in any case.
All in all, I think I have to agree with the assessment so far as well. This game was a step back. I do suppose the game focusing on a male protagonist is a bit of a black mark against it for me as well. I generally don't vibe with that kind of content, though I can understand why there might be a lot of people clambering for it. All in all, I don't think this is one I will actually be buying for once. I have supported this dev before on their last 2 or 3 games, but I can't justify paying for this one.
And before anyone asks, no. My save sure as shit isn't a full one. I've only gone all the way up to the final stage in one version with one of the girls, Nesica, and have yet to beat the final boss. Maybe the gallery unlocks after you beat them? But I doubt it. And honestly, I really don't have much motivation to try and 100% this game so I'm gonna wait for a hero with a save as well. But hey. If you're really desperate to at least see all the stages and don't mind your girl a bit furrier than the others, I might as well at least share mine. The save goes in the save folder which is inside the resources folder and is only for the みるみる乳剣伝 -つんでれ兎とわんぱく勇者- version. Go nuts, i guess.
