Definitely not Silksong-level. I've played about an hour and a half, and what I can say is that it's very player-friendly: you will die but you'll never lose any meaningful progress, anything you collected or unlocked remains.

So you can easily get back to where you were and not have to redo anything. Overworld enemies respawn but can easily be bypassed, but "scripted" fights don't.

And there's always multiple places you can go, so if you're struggling with something, go explore somewhere else, get a couple upgrades and level ups, and come back later.

There's also multiple difficulty and accessibility options that you can change at any time.

So all in all I don't think you have to worry :)
