This game disappointed me extremely. Heard about this one as one of the best netori games and expected much better product. But still, hope I'm able to give a fair review comparing it to other netori games.
Plot is obviously full netori and you MUST conquer Chiho (main LI), your soul depends on it. But is it really that great? Game is very shallow, I didn't feel any bond between MC and LI. Just a fuckfest with too fast pacing, where you can bang LI just after several days. No teasing, no conquering, no convincing, no knowing her better or exploring weaknesses, NO SATISFACTION. At some point I thought it's a bug and started looking for walkthrough, but unfortunately it's a feature. There are also no choices, plot is linear and you MUST make LI a whore who fuck random NPCs to progress. You can't skip it and keep her only for MC.
Visuals are nice, much better than I thought (not a fan of pixel art, but I liked it here, combined with 2d cg), animations are also ok, although, buggy or sloppy sometimes. Anyway, it's just ok. Not good or great, just ok. There's one huge WTF. Why MC son is a fucking cyclope?
Mechanics and minigames are quite easy. For job you can just do a good run and then you can skip with earning 90% of best income. It's more than enough, because you almost don't need money. The only minigame I had small problems (2 repeats at last level) was with Alice, but it's manageable. However, minigames may be easy, but it's still a porn game and they should always be skippable or at least not in most of porn scenes. Being interrupted by minigames every several minutes can be annoying, even if they're easy and especially when you have to focus on god damn arrows instead of on action. One more thing, you shouldn't be afraid of timelimit (30 and 90 days), there are hints and game is designed that you can beat it in less than half of given time.
Tl;dr. If you want fast fap with fast pacing and like minigames, this one is for you. If you like deeper story and/or hate minigames, forget about this title, you'll be disappointed.
