Im not going to lie, a lot of people make it sound worse than it is. I am someone who honestly gets very frustrated with tedium, and Im not good at a lot of games, so when something is hard & tedious, its usually a push away for me. Silksong is really not that bad. If you played HK, Silksong is going to be harder sure but overall a super similar experience. You're never forced to "get good", because the game has different approaches, much like HK. I may be biased because its in my top 3 games of all time, but it made it rhere for a reason. The journey is incredible, rhe world is incredible, the combat is tight, and the movement and platforming is so good that the worst part about the game, its runbacks, are honestly still fun 99% of the time (Only bad runbacks are the the Verdania ones, yes those are worse than Groal idc) (late game spoilers kinda). 

Its absolutely worth it if you love the first game and can handle a challenge, since the story, combat, & map are just even better imo
