I agree with you. These games are difficult on purpose and its a lot of fun is in rewarding the player with getting good. But if it is too difficult from the get-go, newer players will bounce off the game.

What I would have liked in Silksong is for the devs to remove some of the "frustrating" part just at the start: more free benches, less hp for some enemies, less flying enemies in platforming parts etc. Once the users have unlocked abilities and are used to the movement (and hooked in!), crank up the difficulty to what it is now.
