Doing a little god killing | Hollow Knight

Hello Everyone! I am finally here at the final endgame. It's been a long journey, but the journey will be long yet. I have a bunch of boss rushes and the only ones I've done successfully before were Kirby (not a small feat, just curious of why). Streams Wed/Sat for main game, Fri for side game, Mon for Celeste, Tue for Metroidvania. Obligatory LIKE, COMMENT, and SUBSCRIBE! See y'all later! Comment Q: What game has your favorite 'Boss Rush'?
