Since Valve hasn't reviewed ExploJudo yet, I'll happily report that the game is 100% Steam Deck and Ubuntu compatible out of the box, exactly like Schwarzerblitz.
There are no known Steam Deck/Linux bugs except a shader issue that has happened to a very limited number of players and whose solution is detailed here:

So, get ready to explode people on Steam Deck too and let me know how it goes!!!
