Haven’t tried it on the Deck to see if it still works/works with its implementation, but I remember reading the Linux version of World of Goo works with but doesn’t officially support (presumably meaning if it breaks anything they won’t help you fix it?) multiple mice if you change a variable in the config file
Fact that it makes the 512 LCD cheaper than the 256 LCD is pretty hilarious, even if it is a “these models are discontinued, clearing out the stock” sale
