Gave this one a try and it was unfortunately pretty lackluster. It was like a checklist for all the disappointing mechanics in H-games for me.
First off it is incredibly easy. You start combat untransformed but this isn't really a risk as you still can fight monsters effectively. Additionally, when you transform you get a free full heal and mana refill. You can toggle starting combat transformed but then you don't get the full restore so it is actually an advantage to be untransformed at the start. Also, two of your skills are straight up a free full heal and a free TP filler. No cost, cooldown, or limit or uses. You have some token spells but they are pretty useless since you can just spam the TP filler and ultimate attack you get at 100 TP infinitely for tons of damage. Big turnoff IMO, if you have to lose to experience any H content then it might as well be a gallery with extra steps.
Second, there doesn't appear to be any H attacks or sexual anything in combat. You just fight the monsters and if you lose you get a scene and game over. No bad states or H debuff either, just back to last checkpoint.
Finally, the "bad states" you do get have little to no impact. Combat doesn't change at all in stats or enemy behavior. The brainwash headset causes you to instant lose when you enter the boss room and then you are back to checkpoint after a tiny scene. The futa one might as well have not existed, it didn't even change the character portrait. These are more of a theme for the level than an actual debuff or game mechanic.
I only made it through 3 floors. Maybe it gets better, but after I saw the pattern and found it uninteresting I moved on.
