I like you went for a puzzle approach this time, unfortunately i couldn't solve it. I thought you had to change the letters in password with the image hints and moth=p but it didn't work.
If you want to try another puzzle like this. you might find it to be a good idea in having an entry puzzle that's incredibly simple to solve. Then the later more designed and challenging puzzles will have the player with a clear understanding of what is asked of them.
Hope to see more fun ideas in the future!
