Depends on what your tastes are. Personally, I thought it was amazing, especially Eika's route (yes that's the one with the happy anal, no that's not why I liked it). I'd say give it a shot if you like/don't mind tsunderes since almost all of the heroines are in some way tsundere. Personally I enjoyed all of the routes except the maid's. It's not going to change your life, but I think it's a really good, happy break from some of the more super emotional vn's. Then again, this is coming from someone that very much prefers happy endings and fairly low drama in stories
tldr: eika's wincest route ftw! She is brocon to a never before seen level (at least I've never seen anyone come close to her)
