A few minor criticisms for this version;
1) During Rina's current max corruption level Misaki's name plate was mildly jumbled into Miskai.
2) Again During Rina's corruption level, I noticed Misaki's ?trim? for her glove was off center.
3) The shading and coloration needs a bit more work: Some of Misaki's outfit pieces (namely mat parts such as the gloves, side skirt pieces, and solid body suit sections) have a very sharp sheen to them that triggers me into how normally these CG models come across as "Uncanny Valley" in how realistic they try to be. Rina's and the other girl's (can't remember her name off the top of my head) revealing outfits are a little to one dimensional in terms of coloration (especially in the previous version), that it almost looks like it is just a 2D image plastered over a CG model.
4) This one is just personal taste but, the dick is comically apparent with how little was done in making it. I could count three simple shapes that were extremely lightly altered to make it (there could be more, I don't have the model to look at to confirm). The head and shaft seam like they are probably half an inch or something farther than they probably should be, and the shaft is too much of a straight rod with how long it is, having a small curve (10-20 degrees might suffice) starting strongly at the root before reducing in the rate of added angles as you go up the shaft, with the angle being pointed away from the balls.
5) The lack of, even stock, sounds for the scenes outside of the default area sounds and music kind of doesn't help immersion when you want to bust a nut with them.
6) The bedroom scene with Misaki drags on for a long time, with the effect animation stopping the player when they want to skip through it for a good 3-4 seconds. May not seam like much, but some people that are gaming will have annoyances when they try to go through a scene and want just skip through when they got what they wanted out of it, only to have their skipping stopped by scene effect 5-10 times (didn't count how many times you used the effect in quick succession during the scene).
A side from these minor criticisms, it is still wonderful work you've done for what you've put out, as usual. Looking forward to your next update, which is more than I can say for other games I've been keeping an eye on where I'm just waiting for it to be finished and for their to be a completed save for them posted, such as "Star Knightess Aura" that has painfully long time for mild corruption to occur and doesn't appear to even be half finished (if the version number indicates anything) and having hours of playtime to it (with probably 75% of it being time wasters).
