Is Blood on the Clocktower hard to learn as a player?

I will be the Storyteller and have been a DnD DM for many years, so I’m not really worried there. However, only 3 of the DnD players will be playing BotC. I imagine they’ll pick it up quickly but for the other players, is it hard to learn?

The players range from mild board game fans to people who really don’t like complex board games with a ton of rules (paradoxically, one of the biggest haters of a thick set of rules is one of the DnD players, so I guess it really depends on the game lol)
