To say this game is "great" is a mere understatement. It is cleverly thought out and does not get the credit it deserves.
The "player" has so many choices. What you choose does matter and there is a variety of routes and endings. Unlike previous visual novels I have played (*cough* being many), the player is greatly involved in this one.
You can design and choose a name for the MC (woohoo!). The music, the art, and -of course- the story itself all allowed me to immerse into the novel, which is very impressive. Characters did not feel rushed and were able to pique my interest.
I couldn't help but finish all routes and am very happy that I did. It is a game that left me wanting more, feeling sad that it had to come to an end. A very rare, but precious feeling coming from a VN.
In other words, download it!
