I generally don't like double-posting... but I like leaving my impressions on a game before I buzz off... so here we are.
First of all, the translation for this one is total hot garbage. Barely edited MTL, and by barely edited I mean that there don't seem to be any MTL related bugs... but that's all I can say. Not that it matters too much since the protagonist doesn't have any personality except pervert while Shizuka doesn't have much to her aside from being a dumb JK with a game addiction problem that also gains a sex addiction problem.
As such, there's not much of a story to miss out on due to the fact that the translation is terrible. Said terrible translation does make the scenes less hot though at times.
On top of that, this isn't really a game. This is a VN made in RPGM, and there's absolutely nothing in it that couldn't have been done in Ren'Py or any other VN focused engine. It's a total waste tbh, because RPGM obviously isn't optimized for this sort of thing. Speaking of optimization... as my previous post notes, there's definitely something off about the way this game uses resources. I have no idea what the heck they did with it, but the way it runs just isn't normal.
Moving on. The smut scenes are nice if you like humongous boobs that jiggle all over the place. The fact that this whole thing is animated is what really makes it worth it. For the most part, the game is pretty vanilla with only one pissing scene and one scat scene, both of which are part of the "visit the school at night" thing, so you can easily skip that stuff if you don't want to see it. There's also the loli stuff too, I guess... except it's not really conventional loli stuff. The loli route involves Shizuki magically shrinking for no apparent reason, but her mind doesn't change in any way so she's just as mature as before, mentally, she's just physically younger... because she's stupid. I dunno. It doesn't make any sense...
Funnily enough, the loli route is the hardest to enter unintentionally, while the pregnancy route is a matter of random chance.
The route split happens at Love Level 4, and the game basically tells you what triggers what. At love level 4, Shizuku has a random chance to be impregnated every time she's creampied. You can maximize that chance by sleeping with her naked and fucking her in the morning and cumming inside. So depending on luck, it might actually even happen after the very first creampie she gets from the mandatory creampie sex scenes that you get from reaching this level in the first place.
The loli route splits if Shizuku has less than 19 Intelligence when hitting love level 5.
I have NO idea what happens if she's pregnant AND is below 19 intelligence. To lazy to check that...
Now, you might be wondering, how does her intelligence drop? Well... Shizuku loses intelligence every time something lewd happens. Basically, the MC literally fucks her stupid. However, she can only get fucked twice a day(at love level 4), between the morning fuck and choosing to do something lewd. So she can only lose 2 Intelligence a day. Now, she gains Intelligence when MC helps her study. She gains 2 Int from initiating the action, and you can choose to continue to help her, in which case she gains an additional 5 int. This leaves you with 2 action points, which you can use to still do something lewd with her, which means that per day, it's easy to end up with 5-6 Int gain even when maximizing the fucks she's being given.
So yeeeah. When I originally reached the route split? The dumb sloot had... 50-something int and I wasn't even trying particularly hard.
ANYway, it's recommended to finish the normal route first, aka keep her above 19 Int and don't creampie her before she reaches love level 5. Funnily enough, she can't get pregnant anymore once that happens. Don't ask why, there's no answer. Porn Magic, I guess. However, the main reason why it's recommended to get the Normal route first is that 1, it has the most scenes. Two, it allows free-play once it's finished and registered. Three, it enabled the gallery unlock if you don't feel like unlocking all the scenes manually.
All in all, pure fap/schlick material with no real substance to it. Great to waste time with. Not so great if you want something more from your smut than pure smut.
Oh, and it's a shame that there's not more material involving Satoko, Shizuku's not quite as stacked friend. You do get a scene where she can be fucked stuck in a wall with MC thinking that she's Shizuku... but how the hell he can't tell the difference when doing it repeatedly, when she has a mole on her butt that Shizuku doesn't have... I have NO idea. Guess intelligence is not the strongest trait in this family...
Either way, not the worst way to waste some time, and this is one of those few artist that can make gynormous tiddies and make them look good for my personal tastes. So that's a plus.
