It's a huge undertaking and almost entirely unlikely to happen but.. how about it! The Switch homebrew scene is very lively and a port of Aranock's client as homebrew would probably net a good number of new players, and invigorate the community. Well implemented touch functionality with a few customisable 'hotkey' button combinations could make for a good experience of the game.

I’m not sure I could click fast enough or select very well on a switch like I do with a mouse. 😎

Haha, it wouldn't be the best way to play but I think it could be done half well. Some especially customisable button combinations could be useful, e.g. cast a selected spell in a particular adjacent direction. Perhaps something like hold a trigger button to zoom, etc.
