Not much here, and what's here is very cringe-worthy. MC is stupid and the dev takes the laziest route possible in every circumstance. Dialogue is very artificial and the scenes are silly. Renders are nice, bar the fact that the baddies are the same baddies (including Lumpy George) we have seen in a bazillion games.
The developer needs to think a lot harder about how his MC gets into these situations. Just having her be a passive victim or a bimbo doing what following every male suggestion is uninteresting. If you want these events to happen, come up with a way that allows them without having the character just say something like "bad things are happening, but I don't want to make a scene." The whole "semen on the pants" thing is also silly. Make the dress code in the school not allow jeans, and you can have the sexy bits without the silly bits.
Unless it is necessary for the plot, don't make the MC a laboratory science teacher because she is unqualified to be a gym teacher. That's absurd - lab science teaching requires the highest level of qualifications, not the lowest. Anyone who has been to high school almost certainly knows this.
I don't review first releases as that wouldn't be far or informative, but I wouldn't rate this more than a two if I were reviewing it.
