Magnificent! It's really, really awsome!
There's many paths to go, you can level up choose the way you want to fight, ally with others, etc. The few characters Borcus (my MC) met were all interesting. Revenir tells a compelling, well thought out story. Sometimes I feel like the story drags a bit, but while it's kind of true it doesn't matter to me at least.
I sure hope the game is not yet again another abandoned project (like Blackgate, The Butterfly Dream, Project Aego, Guardians of ParVa'La, ...), because it really has a lot of potential. I don't just say that, I mean it.
PS: You should include a LGBTQAP & lesbian tag in the description (and maybe straight too?)
