Play
the prequel. It's strictly superior and is one of the best NSFW games overall.
If you've already completed it and want more...
v 0.8.2
The game is not complete trash like it was a year ago. We can now buff spells and inventory, and the bug boss is finally defeatable (instead we've got the moon boss, but more on her later).
But I have two very clear reasons to deduct two stars.
The first disaster is controls. The prequel was keyboard- (more like console-) only, with 6-8 buttons doing everything, and I mean EVERYTHING. Picking an enemy, infusing a classmate, jumping in dungeons, playing lesson minigames, picking Fae's form and so on. Here half of controls is on mouse and the other on keyboard, and both are fucked up.
The mouse controls are counterintuitive. You may accidentally close the game when closing the grimoire. You struggle to navigate around school, because it's split into two identical-looking halves, even the same garden is two different locations now. (And, of course, half of the rooms from the prequel were relocated just because.) The travel spells and combat spells share the same "Spells" tab, and you always have to turn the page. You've got several inventories, I can't even count them (up to five?), each of them having a separate job. The endless wait for the room objects to shine is the least annoying piece of this mouse control.
And even the good old keyboard controls have degraded. In combat, we're now a melee mage. A melee. Mage. Who can't look upwards or downwards, who needs to rest after taking every step (severe cardio problems), who still relies on the gamey barrier from prequel and endlessly mashes it at the moon bossfight.
The icing on the cake is the lack of tutorial, so stuff like several inventories or finding the jungle dungeon you're supposed to figure out all by yourself.
The second disaster is dungeon navigation + arcana grind + moon bossfight combo.
In prequel, if you couldn't beat enemies, you roamed previous level several times (or played training minigames). The previous level was always the best place to grind arcana and stat increases. With time, navigation was getting better as your field of sight slowly enlarged, while shift-jumping allowed you to skip battles.
Here, if you want to grind arcana, you roam the starter level. It has no walls, few enemies and lots of boobs, which give the same 10 arcana on any level. One run can net you 50-100 arcana, while one lategame spell upgrade can easily cost 400 arcana.
You could also farm arcana with sex, but there's no option to increase sex speed (or I haven't found it). Although sex is the best way to farm ovaries plants (which buff items).
So you don't grind, walk through the whole game and then meet the moon boss. Who crushes your shield like a beer can (with no way to train max shield size, although it was possible in prequel). So you mash shield spell, evade her attacks, and then she just starts carpet-bombing you. You renew shield, heal and cure bleed (that's three different spells with sizeable schemes), while she sends a 3x3 nuke every three seconds.
Okay, that's a nice boss (I wonder if the final boss can be any tougher). You need better spells, so you go grinding... and get stuck in the worst grind in videogame history.
In the middle of which, it's hard to skip dozens of pointless battles, which was easy in prequel.
In general, the game could be quite good. But, for now, it's unpolished as hell (and that's better than it was a year ago).
P.S. The best spell is the second last one, "Shadow Claw". Out of 16 spells, you only need two: this one and the shield one. Don't waste arcana on anything else.
