It remember me "Divine Divinity" !!!
The combat is a bit messy, the companion goes on desperate attacks while I run away from an impossible combat but there is a real charm and experience in this type of games.
The map is quite massive and the difficulty is challenging (playing pn easy to not get mad :D )

edit : I lost my 27h save as I miscliked on the "start a new game" !!!! :\
I recommend to be extra cautious with saves !!!
