I'm new here and I was thinking about starting to run this game, and I was wondering if there were any noteworthy differences between the versions of the game found on itch io and Steam.

I'm aware this is probably a stupid question, but one I thought was worth asking just to air on the safe side.

Don't worry, there are no stupid questions (and if there are, then this is not one of them). As far as I'm aware though, there are no differences whatsoever between the Itch and Steam releases. Hope you enjoy running the game!
