The game text's font seems a bit weird sometimes (like a bit glitchly). Nothing major though.
The videos couldn't be played, a pattern was shown when the videos were supposed to be played but the actual game videos weren't played. After researching this a bit I found that the game uses Windows Media Player 9 codecs for the videos and those are an issue with proton. By exploring the game local files and going to the "Little King's Story/data/0_movie" folder, I re-encoded the videos to a codec that works correctly with the following commands:
for i in *.thp; do ffmpeg -i "$i" -vcodec libtheora -qscale:v 9 -acodec libopus "$i".mkv; done
mkdir original-movies
mv *.thp original-movies
# rename *.thp.mkv to *.thp
for i in *.thp.mkv; do mv -- "$i" "${i%.thp.mkv}.thp"; done
After these the videos play correctly!
Works well as-is with zero tinkering except on the initial launch window, change the control method to Generic Xinput.
No major issues found
Font size is too wide so text does not fit in boxes and often overlaps
If some bosses seem impossible, try lowering FPS to 30 by pressing the f1 key

Turn off Intro logos and Intro Videos.
I personally set Refresh Rate to 50, and the fps cap at 50.
It plays as good as it needs to, and anyone wanting to play this game on the Deck, let alone linux, will have a good time, no doubt.
Game crashed with 2h played. And I had to deactivate the logos of the start and the videos to play, but no more issues. Playable.

Game starts after doing protontricks 390310 dlls d3dx9_43 dotnet40
and removing d3dx9_43.dll
from the game's directory, but crashes with a D3D error after the intro movie. Can't be bothered to investigate further.
