Okay, I swear this isn't a bait post, but can someone tell me when does the game get hard? I'm not saying this as a bad thing! But I heard a ton of people saying it was mega super hard etc, and I just did the Lace boss, which isn't far into the game, but I haven't died once so far and since you can just perma heal, I never felt in danger once

Does it get way harder after this? I'm having fun, but it's been kiiiiiind of boring until I got the sprint, which makes the game way more fun now with combos and stuff, but the difficulty is still not there
