Wasn't sure if I was going to hand out a 5 star rating, I'm going ahead with this one.
First - Story. Interesting concept, I know there are games with the school theme, Annie's School Days has that. What it also offers is a number of story lines (quests) that keep you interested and involved. Not to mention a few additional bits and pieces that give you hope for bigger things to come - anticipation is a good thing.
Second - Grinding. yes, yes, there is grinding - it's a game. Considering the early stages of development, I would say there is considerably less grinding than I have experienced in other somewhat similar games. Of course, as you get further into the game-play you reach a point where there just isn't more content yet, so of course there will be repetitive scenes. In those cases I have taken the time to investigate other areas to see if I have missed anything interesting or fappable.
Third - Game play. THANK YOU! Thank you for including a solid rollback function AND instant saves. Without a comprehensive walk through (which I am considering developing with permission from Mobum), it is insane to expect players to not want to rage quit any game with multiple choices and/or story lines. While the interface is not the best I have ever seen, the save game and rollback feature are ultimately what make this game so playable - I actually want to spend time with it. There are enough active lines to pursue that once completely developed, I could see this being one of the better games available. One point of note: since the MC is building toward sex scenes with other characters, having that immediately available with Annie helps eliminate some of the feeling of constant grind - it's nice to "get some" while waiting to "get some"
Fourth. Characters - Again, THANK YOU! Given this is a school I like the variety of body types, ages, personalities, etc. It fits with the theme and should continue to be developed as such. While I am never too keen on playing the part of a "wimpy" MC, in this case it works (as long as his development continues make sense; i.e. the MC swims and actually gets better at swimming, the MC reads and actually gets smarter, etc.
Finally, I am not certain how in depth the Lust, Submission, Shame, etc. stats are, or how much they affect change in the ladies behavior - I can say I noted that it seems to progress the quests fairly well, although there appears to be a cap on certain stats as they are tied to events:
For example, once you progress with Mia on the Sex Education quest, using reading, swimming, etc. as a means to build Lust and increase Shamelessness, it seems as though the swimming is capped as an activity to increase Lust - it increases Lust, increases Lust, then BAM! No more stat points I am guessing it is because more development is required so not a real knock against, just an observation.
Earlier in this review I mention having sexual encounters with Annie to offset some of the grinding - If I could make one suggestion, either more of this, or create a repeatable event with one of the other girls to give it a bit more fappability early on (selfish I know).
All-in-all one of the better games I have played.
