>Saying that it's a feature of the genre is definitely wrong.

good thing I am not saying that then

The point is that if you see "roguelike" then those features could be there, not that they necessarily will be there. We are talking about a genre, which is a pretty general thing

An FPS could have grenades, but it might not. And including grenades does not suddenly mean it is no longer an FPS.

Steam does list Dead Cells as both a roguelike and a roguelite. So yeah, you literally will find these features in this genre.
