This game is something worth to check out despite being old game.
This game have mainly 2 way to play, first as virgin with strong weapon/skill, or not virgin with easy money. While in order to keep virginity will lost some chunk of event but actually fun to play than thought due to not all event straight to lost virginity and you still can do it with virgin run. But I recommed to play it normally and let virginity lost in process naturally without trying to make it happen.
This game have a lot of event that hidden and likely to be miss if not use guide this is most likely to be con, but I find this interest to not clearly show icon to every event npc, talk got H and finished like 95% of modern H game. And this game is very slow corruption make is feel like virginity really matter, and can also lost easily with some random monster when you fight when cloth ruined.
In term of combat. I think is decent but is depend on virgin or not. there are more skill to learn via boss, event which will help non virgin run, but barely help virgin run due to they will already have best skill. Some monster can make mc lost virginity if clothes ruined and they use certain move, but is not like clothes ruined=instant lost virginity at all. Last battle is very crazy difficult for me no matter how you play and required grinding not like other part of the game that you can keep going while not feel too hard or too easy, But I feel like is doesn't matter much, I'm enjoy the journey to that point more than actually finish.
Map is quite large compare to most rpg game I play, design is good when I'm in forest is feel like is really forest, is huge, confusing. When going to each place they have some distance between city.
About CG is decent quality. not most gorgeous or anything but good thing is there not recycle the same pic in every event like some game and just change dialog.
TLDR: If you have time, like slow corrupt, hard to get event is quite good experience that I feel like not many game can offer. Give it a try.
