別バージョンのprotonを用いたときに、ある場面で画面が真っ暗になりました。 When I used a different version of proton, the screen went black in one scene.
Protonのバージョンと起動設定をいじれば問題なく作動します 神ゲーなので是非遊んでください!!
If you adjust the Proton version and startup settings, it will work without any problems. It's a great game, so please give it a try!!

Xbox core wireless gaming controller (connected via usb) is not detected by the game on boot. I can get it to be detected properly by doing the following less-than-elegant solution each time the game is run:
- Boot game
- Enter the steam overlay and select controller settings
- Disable steam input and return to the game
- Enter the steam overlay and select controller settings
- Enable steam input and return to the game
- Controller should now be working
I'm not ruling out that this is just a configuration problem on my end for whatever reason, but this is the only game with controller support in my library that I've had to do this with.
Worked flawlessly on default settings

Sometimes windowing would make the window size 640x480, sometimes it would be 1280x960. The default size for windowed mode on Windows is 1280x960.

Crashes on start

Runs without problems out-of-box

Somehow, this game worked better on proton than windows. At launch there were numerous bugs, but somehow no linux user i have talked to, or i, have noticed any issues. Honestly impressive, considering the issues the chapter 1 release had in wine (hyperspeed mode)
Game ran just as you would expect on Windows.

For a weak system like this it worked pretty well, so far there only a small delay after starting the first fight of the game.
It's not much but it bother a bit.
Significant drop in fps on fullscreen.

Great proton compatibility, only minor inconveniences that a normal gamer would not notice until it was directly pointed out to them.
Moving is noticably slower, enough to make some bosses harder than they should be.

Proton doesn't seem to run Deltarune well, at least for me.
Game runs at about 20 FPS, which seriously harms gameplay. This doesn't happen on Wine, however.
Crashed only once during the "chalk" scene
Ran perfectly out of the box with Proton Experimental
Have had 2 crashes after extended periods of playing

Works out of the box, but crashed twice and noticed minor sound glitches during the credits.
Audio overlayed during the credits scene
Crashed twice during my ~6 hours playthrough

Runs out of the box perfectly, has no visible issues throughout entirety of gameplay.
Crashed once on my initial playthrough near the end. DId not happen again after a game restart.
Only Chapter 2 was played at the time of writing this report.
