Welp. I picked this up because it's been in my backlog for a while... and...
Well, it's honestly an utterly meh game. Completely mediocre. The story is nothing special. Just your typical "monsters exist and bitches have to fight them", combined with a dash of "humanity makes things worse for itself, always". Not much substance to it.
The gameplay is nothing particularly impressive for this particular RPGM engine. The ability to pick skills is not new. Though this is the first time I see a system like that which uses the character's XP... Unfortunately, this is probably the first time I see it in an H-game because it's a fucking stupid stupid system that makes the game even grindier than it already was. The combat isn't anything new either, and you're mainly gonna face challenges from the fact that bosses and the like are utter stat-sticks and taking advantage of resistances and weaknesses and whatnot doesn't take you very far if the enemy still out-stats you massively.
It's not a bad system per se and the gameplay isn't terrible or anything... but I've definitely seen better in this particular version of RPGM, in terms of both newer and older games.
Now, the real problem that makes the game mediocre is that the way it integrated the H-content in the game, as well as the nature of the H-content is overall pretty meh. I have nothing against game-over-rape stuff, but, if you're gonna make each of those a bad-ending, those scenes really should be a tad longer than they are. Being as short as they are means that they're pretty mediocre, and given how long it can take from one to the next, they're not necessarily all that satisfying to get.
The problem continues with the fact that the game tries to dip into corruption and NTR of all things... but does so in a way that isn't great with either. It has this even more dumb than usual plot involving a janitor blackmailing Otome if he catches her masturbating in school... which somehow works even though she's an exorcist and the game makes a whole point of those not growing on trees and being important and all that jazz... This is made all the weaker by the fact that Otome's boyfriend is barely a thing... On top of everything else any other H-content in town or whatnot depends on raising Otome's lewdness value... and doing the Janitor stuff is the primary way to do that.
The only other option is to buy drugs... which cost 10k a piece, and sure you get 1 for free, but you still need two more if you want to trigger even the lowest hanging fruits in terms of Lewdness requirement, and that one event doesn't give you enough lewdness to the next ones, which means avoiding the janitor is impossible if you wanna do the lewd stuff.
Even weirder is the fact that there's an entire bonus dungeon that's locked behind Otome's lewdness level, for some reason...
Honestly, it feels like the dev was trying to dip into a bunch of things and ended up failing a lot. It's just... not great.
Oh well, this game isn't the worst way to waste some hours... that said, for most people, I recommend cheating stats/levels/whatever, because it's not particularly worth it. The grind to meet some of the challenges isn't hard or anything, it's just tedious.
