If you liked the first game,
A Rift in the Crypt, then you will probably like this game as well.
The NTR remains hot, and it's always nice to see reverse NTR (where the guy is the one stolen by another woman). The story is even better this time around and it's clear the creator is setting up for their own porn franchise.
Don't worry though, if you haven't played the first game. While their are several references to the first game here Mirage is designed to be a standalone game. So if you're curious and looking for a good NTR and reverse NTR game then I would recommend this game.
With that said I do feel the game's story has left behind the actual sex scenes.
So I was thrilled to see the creator challenge themself with this second game. Instead of 6 days we have a whole month this corruption takes place in, instead of only 1 love interest getting NTR it looks like 2.......but sadly both these things prove to be a disappointment.
While 30 days is a good amount of time to have a lot of sex scenes in it, that just doesn't happen. Instead we largely play up the same beats sex wise as Crypt. That is definitely a problem since the scenes in Crypt was paced as a 6 day game, so what does the creator do to fill up the rest of the time?
Well throw in a lot of pointless filler sex. This is where the second LI Kotori comes in. It's very weird, she's clearly setup as the "sister" arch type who has unreturned feelings for the MC. They even give her a lewd stat page like Luna so everything points to her being another LI but then they just straight up delete the stat page and throw her aside. Like I thought we were going to do this neat thing where she's trying to seduce the MC too but the villain is also seducing her and turning her into a demon but no that doesn't happen.
All of her scenes were just so disappointing since the villains just flip a switch (mind blast) and she instantly becomes a slut, no buildup, heck there's not even real corruption there since its clear she's subconsciously against the idea. The villain makes a point of stating this but he honestly doesn't care enough to slowly break her in since his main targe is Luna (other LI). Then mid-month the heroes free her and she's largely just forgotten about sex wise from that point on. She still plays an important role in the story but she lacks any sex scenes in the second half of the game.
There's also ANOTHER seducer character besides the Witch, but she's even worse (I didn't bother remembering her name). She has zero connection with the heroes and isn't interested them at all sexually. She just sleeps with the other guards......it's literally filler sex until we get to the good stuff with Luna and the MC.
At least she contributes a little to the story but sex wise she does nothing and the game would have been better without her scenes in it.
To Mirage's credit I do feel the reverse NTR part was better than the first game. Adding more scenes and buildup to the MC getting seduced by the Witch. But the normal NTR part is hurt by the game's pacing since no new content was put in there which is a shame! With the added time I was expecting their to be more scenes of turning Luna into the base's slut, with her secretly seducing the guards, or acting more slutty in public.
But no, it's pretty much beat for beat the same as in Crypt. (For those who haven't played Crypt I'm taking about your standard "Kiss, grope, handjob, BJ, sex, slut") Now to be clear it's still well written, but the game's pacing hurts it. Honestly this game should be cut in half with all of the fluff in it.
The other major issue this game has is the degradation of the actual game mechanics. Again it seems like at one point they were planning on having this mystery mechanic where you're gathering clues to prove the bad guys are bad before they seduce the heroes and you have to manage your in game time.
But no, this is basically a VN with the occasional choice on who you want to sleep with. There is no thinking here, just the occasional annoyance of searching the map for characters.
And really only your last choice in the game matters (which ending you want to go to). On one hand I did like the fact the game does this since it makes getting the other endings very easy but that's only because I realized I didn't want to play this game again.

Which I think shows you that the game has a fundament design problem.
Overall this game is fun and a good time, but I do think it's flawed and a sign that the creator is focusing too much on the story when they also need to be thinking about the smut scenes and game mechanics.
Hopefully this trend doesn't continue in the third game.
