From the various Erotic NSFW game, this feels like the only one with a proper indepth Turn Based Combat System that is also quite challenging.
Altough most would just want to get into the meat of the characters and not the difficulty, I have to applaud the effort done to the combat and progression of the game, feels more then a NSFW game ifywIm.
(Bit of a shame there are characters with supposed Affection Progressions not even starting yet, but I digress, It's a nitpick from mine, do whats best for the game)
