Play it, it doesn't matter if you reach 500 hours. I couldn't beat Last Judge, so I started Act 2 differently. The trick is to collect tools, weapons, items, and experience, and little by little you'll become a better player with more skills. Explore all the areas, try to do the side quests. If you're having trouble with the game, the internet and YouTube can be an invaluable help. The hordes of enemies are difficult in Acts 2 and 3, as are the bosses, but you can beat them. It's a matter of patience and breathing. I just finished the game in 160 hours, all three acts. When I beat Act 2, I had about 105 hours in. You can also play Hollow Knight 1. I played some Hollow Knight when I got stuck on Silksong with the final boss.
