The real boss of this game

I honestly prefer to face 10 Isidoras or any other Boss than these SHIT challenges from bloodstained, what a horrible, boring thing, frustrating because this game is not a platform and the penitent is totally clumsy with these stairs falling all the time on the spikes, not to mention the fireballs (or magic) that are positioned just to knock you down on the spikes, that's all that's needed so I can ascend my save, and I'm seriously thinking about not completing these challenges due to upset about that
