I must say, I found Hollow Knight to be perhaps too hard at times (bloody Watcher Knights!!!!) but the sense of achievement I got from pushing through and after about an hour and a half of trying, beating the Hollow Knight, was just about worth it.
I am very much a physical media guy so will be waiting for Silk Song, if it is tweaked by the devs along the way then that’s fine by me, I don’t think Silk Song will ever be turned into any ‘easy’ game, so it’s seems a little unnecessary to get bent out of shape.
