Over all great game, only problem I have with it's ending.
1.MC was never told that this was not a "game", but was literally isekaied every time he went into the machine (you learn it by doing 2 bad ending or noticing that by interacting in illusionary zone people actually react to it in real life)
2. Mc is is literally cut out from friends and lovers/family that he made there. While it might look as happy ending he is going back to office work....
3. They did not use the fact that those spirits were literally able to communicate with him outside the "game", this could have been explored more and be used as a way to make him realize that this world is not a "game".
4. This might not necessarily be bad, but all real world npcs lack any substance, you dont actually interact with them in any fashion, like gourd is not even in normally visited place, they could have placed her in front of train/metro station and be there and interact with player few times.
Also While I know that it would be cheating... they could have been doing something in real life, as this already is harem type game.
5. White oni exists but we can not do nothing about her, we can not find medicine for her, or make it. There are no scenes with her, nothing.
So main problem, MC is truth cucked. Mc is cut of from that world. Real world is sort of unnecessary... Like you need to eat breakfast and dinner everyday, which only wastes time as dialog hardly changes.
