I have played RJ01236357. It was okay.
The gameplay was fine. I'm not a huge fan of how all your skills are cooldown based and it makes me feel like the dev plays too many ASSFAGGOTS. Your back dash only has a tiny window to activate i-frames and dodge though attacks which isn't the kind of gameplay I'm a fan of. Most normal enemies can be handled by being aggressive and using your other offensive skills at least, and check points are frequent enough that you don't need to be too perfect with it. The game did seem decently balanced for the most part, which was slightly surprising since I recall the very first beta version being kind of shit. There's only 4 stages but stages 2 and 3 are both pretty long so the length is about average for an ACT. There's a difficult bonus boss too but I didn't bother with it.
The h is good. Most of the h is h grabs from enemies and animated GoR CGs. There's a good mix of humanoid zombies/mutants and some tentacle monsters, as well as some succubus too. Between each stages you get a scene too, which is mostly yuri between the protagonist and the scientist. But for some reason one of the scenes is both of them getting fucked by a big muscular black guy. It's pretty strange as a one off, and despite the scene being him blackmailing the scientist as her superior officer he completely disappears from the story after the scene and is never mentioned again. It felt completely bizarre and out of place.
Overall I give the game a 2/5. While the think the game has some good parts and is higher quality than some of the other games I've played something about the way its put together is off-putting so I personally wouldn't recommend it.
