I've been following this game since damn near its debut, and have been beyond impressed and further sucked into the world and characters each chapter that was released.
Now to get into my review, with will be as spoiler free as possible.
Graphics: Great. the first chapter was rougher with its renders, especially lighting making Kira look greasy, though DriftyGames very obviously improved vastly between every chapter, by the final chapter looking amazing. Though admittedly there are still some rougher renders in the later chapters but they are easy to overlook for the most part.
Music: There is a lot of different song here, and they are all pretty good. Cant say too much more here since in tend to play my own music or other stuff while I read so I only heard some of it.
Sexytime/Lewds: one of the games weaker points. Not bad, but typically much shorter scene and often you can be blue-balled by the dev (which he happily points out at one point!) Renders for the sex stuff varies from pretty hot to feeling a little rushed. If the sex aspect is the MOST important part then you probably will be disappointed. In many ways this is a Story to tell masquerading under the moniker of "porn game". Though despite that, the sex aint bad, just clearly the story takes the front seat while the sex is in the back. A lot of really good Lewds as well honestly.
Story: AMAZING, game starts slow for me until Cece is introduced, then its great until the end. I love that It really does try to actually ground a lot of what happens, even the more far reaching stuff. This game has a LOT to spoil, thus I wont say anything more than, If the story is among the most important things for you (like me) then this game is top tier. This game and its Dev had a very clear and defined story to tell, and it is done near flawlessly. Keep in mind that this game does have several pretty heavy moments.
Characters: When I played the first chapter 2 years ago, I swore Cece was the only character I was going to really like, however, all of the character are really great. Cece still being the best by miles, but all of the females pack reason to like them and are pretty well fleshed out. Where I want to to point a special attention is to the guys. Its pretty rare to play one of these games and actively like the main character. This one is a bit of an airhead, but never is he a major push over, nor a overly pervy Piece of shit, even having the option to play wingman for his best friend (who is also pretty likable and glad he was given the treatment he did).
Final thoughts: The game is really great regardless of its sexual aspects and would be just as good if they were absent. if that doesn't sell that game by itself honestly its you who is missing out.
The characters are endearing as hell, the story is among the best you will find on this site, and the music does its job and there is a hell lot of it. Just play the game I promise you will not regret it.
Personally pumped to see more about the next game U4IA
