A masterpiece !
A psychedelic trip with a very interesting lore (with many supernatural stuff, time shenanigans,...) that is introduced slowly, but with a lot of foreshadowing.... once you will have played it once, you will want to replay it again and again to catch all those hints ! The sex scenes are late to come because they always fit in the history and make it advance, but when they come that does strengthen massively their impact, and they are absolutely amazing.
A main theme of the game is about overcoming one's traumas. So it's an emotional rollercoaster, but in a very healthy way because, how dark some passages may be - and God now some are dark - at the end of the way there is always light at the end of the tunnel, and some characters we begin hating the most finish being the most lovable once they have overcomed the traumas that made them act so badly...
The MC is a very wholesome and caring person, who always see the best in everyone, and will always put the others ones good before his, willing to take the worst risks to save them, in all the acceptations of this word...
And the art ! It begin as very, very good... but the author goes on learning as the game progress, and the progression is awesome, the last chapters are really, visually speaking, a masterpiece !
But this is not only the case for the visual aspect, it's the only word I can find to describe this game :
A masterpiece !
