After sitting with it pretty much all weekend and playing down multiple paths (One for each of the girls plus a poly one), here are my thoughts on the game, in no particular order.
The music is fantastic. Having the background tunes going while navigating around the school is very nice. There's a lot of different tracks as well depending on your location and things like that, which is also a huge plus.
The art is spectacular as well. I'll admit, it did take me a little bit to come around to the 'realism' type drawings for the girls, but it feels natural and is done well. There's already been talk of "touch ups" on the art to make it look more polished, but as it is for a first release its excellent. The backgrounds for everything look sick too.
Customization is good, both for Null and for the girls. There's plenty of different outfit combinations you can conjure up to have them looking however you want. The clothing menu for the girls can be a little confusing though, perhaps adding a point explanation would be helpful. It would also be nice if there was a button that would just strip them to being nude so building new outfits would be easier.
More clothes are always nice too, but i think those are already planned
There's a handful of different hairstyles too, both for the hair above and the hair below

The pubic options in particular i think are well done. They look amazing and there's a style for everyone.
I'm a little torn on the sex stuff though. I really enjoy the UI during the sex scenes, the list of positions is quite impressive and i think i remember them saying more will be added in the future, which will be amazing. However, something about Null's presence during the sex scenes feels off. I'm not sure if its the animations, the angle, or something else, but its different.
Some things that I personally would love to see is i wish there was a pullout option after climaxing where the girl just lays there while you decide what to do next without null in the picture. The doggy style i think could benefit from being zoomed out just a tiny bit more, it feels like a LOT is happening at the bottom of the scene, especially if you use any toys. Speaking of toys, a transparancy option on those would be nice too.
Overall, i love the game. Obviously everybody is going to have their own wants and desires for what they would like to see (Clearly me included), but the Dev team did an AMAZING job with their first release. It felt very well done, well polished, and exceptionally fufilling to play through. I believe they accomplished in one release what other Devs fail to do through an entire developement process. I don't often support things on patreon, but this one was a no brainer with 0 hesitation. The future is very bright for this game and i look forward to seeing it.
