I enjoyed playing the game. It's well made and such.

For one thing, I liked the sprites for the characters so much.

But there's some minor issues that I hope to get fixed in any upcoming updates. 

Translation to English is a bit off in some places. But I can understand that since it was translated from Korean as I noticed in several occasions.

Other thing to point, is some mistakes when people talking in dialogue (Like in Nino Route for example, Miku was talking to Fuutaro in the rooftop, but the names wasn't reflecting on who's talking.) it got me confused for a moment before I figured the order out.

Overall experience is 8.5/10. A Really good "Go-toubun no Hanayome" fan game.
