Works pretty well, with new proton version NOT have any crash anymore and purchase in game works.

[ tweak, tested by me several times ]>*** For any reason the game will start with black screen if you use the defalt installation path set by steam; to avoid it, have to create and choose other installation path that not contains any dot, space or special characters. After that the game runs fine. ***

[ not related ]> Sometimes you get the game run in speed up or freeze, then move the game window around to back to normal (this even also happens the same on MSwindows, and NOT related to wine/proton, but with bad port of the game from mobile to pc. )
