It’s quite hard to give this AVN a very good score because while it has its great moments, it also has a lot of flaws and boring moments.
Well, let’s start with the boring ones, the first 5 chapters in fact, where literally nothing happens, the MC finds a strange book, him and his friends play a role-playing game once a week (you can skip those parts, they add nothing to the story) and that’s it. This is also when you can choose to start a harem or stay monogamous. Don’t worry about all the little points you can gain in the first chapters (sub/dom/share/love/etc), they will never be used, like NEVER.
Then comes chapter 6 and the real fun in a fantasy world, the one from the game you were playing with your friends. A lot of adventures and discoveries where you meet pirates, mermaids, orcs, fairies, and more. This is the best part of this AVN, where each choice finally matters, but it has some flaws too, mostly incoherences in the script, no big deal though.
Then comes the 2 endings, good and evil. Well, the evil ending is cut short, no epilogue, the MC takes the decision to stay in this world and... THE END. The good ending has a very short epilogue showing the MC marrying his pregnant girlfriend and… THE END. It’s a real shame that after spending 4 years on this VN, the developer did not care more for its endings, as if he wanted to move onto his next VN already.
