That's a great game according to me. It has some flaws that cost it the last star but honestly giving it a 5 stars won't be a scandal!
1: The characters are what make it so special according to me! We get to be intimate with all of them, they seem quite real and human. Nice work
2: the graphs are one of the points not perfect for me. Some characters are awesome and so beautiful and some are quite meuh/average... I think about kira for exemple, linda and robin too are lower level than others. The MC is quite handsome but i got chocked when he says his age at chapter 5.... That's BS.
3: The story is interesting but too short for me, it is a little bit too much condensed. I got issue with the chapter 4 and the choice the game ask you to do. It seems too rush out, too soon! I didn't want to choose so soon
I whish i could have fun a little before making any choice at all. Having fun or discovering a little more the characters. I don't see if i'm clear but that was too soon.
4: This one is a big NO for me, the side quest are so difficult to complete without walkthrough. I missed so much content and i have searched for hints in the games to make them. That's a shame. I think there is work to do in this area to make them more obvious. In fact, that's not a life or death matters but it made me so furious and frustrated so that was THE reason i give this game 4 stars and not the 5 it can deserves. If you need an example, i think about the pin code of the robin's phone. I'm sure it is hers nickname's number but i couldn't make it or even try it...
5 The musics: they are awesome, well chosen and all. Congrats that is brilliant!
6: Replayability: Not really great this game have a BIG BIG choice out of the blue but the rest is correct.
