Hint 4
Bucket policy is:

  "Effect": "Allow",
  "Principal": "*",
  "Action": "s3:ListBucket",
  "Resource": "arn:aws:s3:::s3game-level1"

Think about what credentials you need to use with AWS CLI to get a list of objects in the bucket

No hints anymore. :) Get the secret code, and use
https://s3game-level2.s3.us-east-2.amazonaws.com/level2-<THE CODE>.html to get the next Level...
