I'll take your comment as a vote for adding it! It's not always straightforward for such mouse-driven games, but doable.
Curious, what's the scenario you'd use it in? Steam Deck, couch + TV?
Yes, my shoulder is busted from too many years with a mouse. I used to hook my laptop to the tv, and now my Steamdeck. I managed to make Slipways work by mapping the mouse controls to my controller, but it's not perfect.
