I'm gonna say right now, its incredible. Even if you HATE ntr, it's incredible.
Pros:
-Multiple endings, but you don't feel cheated out of any of them if you choose a specific route. Once you "finish" a route, you can play a bit of "endgame" content before choosing to go back to the "branching choice".
-FMC is beyond hot. Her personality is professional/resistant, her body is amazing, so on.
-The corruption is great. It's evident that she's resistant to whichever route she's on, and you can even read her thoughts in the menu. Every day, her thoughts change, so you can slowly see her thoughts become more twisted and lewd. Plus, if you read sexual stats, you can see what she's wearing under her uniform. At first, it'll be basic underwear, but as it progresses it'll turn more depraved.
-It's a game where you pilot a mech, but GapTax understands that people are here for porn, so the combat is STUPIDLY easy so you can play with one hand. On that note, the game is extremely straightforward. During the day, you do a task, and during night you do a mech fight. Rinse and repeat until FMC is fully corrupted.
-The recollection room is one of the best in ANY game. Each "rival" has their own row, and standing next to each "cg bubble" shows a highlight of what the cg is. There are "teleport pads" to use to return to the middle of the CG room, if you don't want to run all the way back. There's a button to fully unlock every CG, but the game is so great that you don't want to.
-Translation is great, your immersion is never broken.
Cons:
-You never play as the FMC, unlike other titles. So, you run around while scanning on the radar where the FMC is. You find her area, run to it, and then the CG is added. So, you won't get the typical "cg with text" until you visit the CG room, which can be a bit disorienting, but it can pay off well once you reach certain points. Plus, it does help with the immersion.
-The map feels small, and even wasted. I would love for more zones, but there are only 4. The base, the town, your neighborhood, and the "18+" zone, but each of these areas feel small and empty, with filler buildings.
-It would have been nice to see the FMC slip up a bit more here and there in front of the MC, but for the most part she stays very composed and withdrawn. So unless you're actively checking her thoughts and the CG room, the impact doesn't hit that hard. It just feels like "ah, she's doing this now i guess" at times.
Overall, an incredible game. You can't help but feel a bit bad for both the FMC and the MC, since they're both really good people but are torn apart due to the circumstances, but the FMC is so hot that you end up not caring too much. If this were the standard of Japanese corruption games, F95 would be feasting. Sadly, this is only an exception, but DAMN is it a great experience regardless.
