This is a bit of a general question and not directly related to this game jam. I’m new to itch and plan on uploading more games in the future, and I’m not sure how many players typically play itch games on mobile. I want to be as inclusive as possible, but adding mobile support feels a bit daunting. Any insight or advice would be appreciated.

I don't think it's really expected. Playable in browser is generally good so people don't have to download anything.
