But there are many straight upgrades to items in the game that are not overpowered, because they are arguably more difficult to obtain than the items they're upgraded from. Golden Tools and the Pick/Axe are upgrades to their regular counterparts, the Shelmet is an upgrade to the Football Helmet. Even the backpack itself already has a direct upgrade: the Krampus Sack.
