just curious, how much romance does this game have? also, will it be updated?
Very little romance, actually! The routes are platonic and the main focus is on the mystery. There are a couple of canon pairings and occasional focus on their relationship, though.
There's a coming update that's been pending for a while (it needs thorough beta testing before release) but it only concerns accessibility options; as the game is complete I'm not planning any more updates content-wise.
