Mighty Milton and the Marvelous Mastermind's Maze

this game OOZES charm and immediately comes out swinging with something i love (metanarrative) but unfortunately the moment i got out of the tutorial i got stuck because i couldn’t find a way to progress in any of the puzzles and none of my devices could read the QR code i found in the game files. i was really disappointed because i wanted to keep going and see what this game had in store for me :/ this seems like what if oneshot was good
