I had to "skip" the launcher by renaming it and use Proton 5.0-10, otherwise runs flawlessly

The initial launcher didn't appear, it got skipped. Only reason this matters is that's how you read through the manual which is important. HOWEVER if you already know how to play, then it's not important.
I've been mainly playing this on the Deck and have 0 issues. You might want to fine-tune the controls to your liking but wihtout changing anything, it works just fine! Only issue that I can see is you don't have access the manual to learn the more in depth mechanics.
There is also a dialog screen on start up warning that if you can't connect to the internet you loose out on online features and highscores.

Some crashes when loggin into multiplayer.
Works fine with Proton 8 and Experimental.

use left trackpad as a radial menu
there are some small text but still playable
