leveling up your build periodically from a randomly selected set of options

The bosses are also randomly selected

Those are neat and trendy features, but I don’t see how they make it anything like Rogue or its ilk.

These days when people say roguelike they just mean a game that divides its gameplay into short, disconnected runs instead of one long, continuous save. It unfortunately has nothing to do with whether a game is anything like Rogue.
