Part of the inspiration of 7DRL is to explore where the boundary between "Roguelike" and "Roguelite" exists.
A specific game cares not for genre; it should always be made the best it can without worrying about labels.
All that said, Roguelike is in the title of the challenge for a reason. This is not meant to be a complete free-for-all; your polestars should have "Rogue" somewhere in the mix.
