I don't usually play games like this but I am happy I gave this game a chance. I had never played an hentai game like this before because I thought they were all bad, but I was wrong about this particular one.
I really enjoyed the gameplay, lore, and all of the voices. I enjoyed collecting all the items I could and finding all of the fragments. I also enjoyed the various "animations" that play out when you get stunned, and the game over screens were quite entertaining, but it starts to get a bit boring when you die to the same enemy over and over and get the same scenes over and over, but for the game over screens, you can just press Z.
Overall, it is a game that I will definitely support if I can and I really enjoyed almost every aspect. (loved the boss ;)) The characters are funny, the H scenes are great, almost everything you could ask for, and this is coming from someone whose never played a hentai game like this. Cant wait for full release!
EDIT: The game over scenes could be a good thing to add to the gallery, and a sound test with the games soundtrack would be great!
