Amazing scenes. I found a warp to Star World (yeah, I’ve played SMW a few times before…) and worked my way around that, finding all the secret exits and ending up at Bowser’s front door. Chose route 4 and route 5 through his castle, and reached him without getting hit.
Then it was time to kill Bowser himself, who was the easiest thing ever, ever, and I didn’t get hit there either. Game over, win!
