I made music of this game based on only synth inside chuck, but realize that it could sound not so good because lack of included realistic instruments. Chuck has unlimited possibilities but I am not so good in making realistic instruments. So I decide to make loopbased system and I tested it in another project https://evgenidoudar.itch.io/resque-miners which is particiate in https://itch.io/jam/gamejam-2020-ad Jam.
