These issues also occur on mobile for me, so appear to just be an issue some users have
Game doesn't let me start playing without being on protonGE (failing with error 395), but works great with it.

ingame videos do not play. Playing online also crashes the game but I cannot say whether that is a proton issue or not.

With the video fix, the only issue is the crashing, which only happens when returning to the main menu.
Game crashes when returning to main menu from a sub menu
All in-game videos are WMVs, which gstreamer can't handle. To fix this, reencode them to a supported format.
Run this in the game's asset
folder:
mkdir out; for f in $(file * | grep Microsoft\ ASF | tr -d \: | awk '{ print $1 }'); do ffmpeg -i $f -crf 19 -c:v libx264 -f mp4 out/$f; done; mv out/* .; rmdir out
Default keyboard controls are WASD + HJKL, with L as the "okay"/"accept" key.

Video is missing. Which makes the tutorial unwatchable. Switching to ProtonGE froze the game.
Missing video.

Not recommended at the moment.

So far has crashed after every match, might be related to me changing settings after each match.
In game videos do not play, displaying a test screen instead, likely gstreamer problem
The default keybinds are WASD + JKL, with L being the default "okay"/"accept" button.
