Getting this game to work was quite the hassle. Regular Proton 7 works without most of my described issues, but pre-rendered videos don't appear (replaced by color bars). Proton GE fixes this, at the cost of plenty of other issues. I found that 7-14 crashes, and anything I tried more recent than 7-25 didn't work at all. I didn't granularly go version-by-version though, so perhaps 7-35 or another earlier version would've worked as well with less issues. An excercise for the reader.
