so i've noticed the extra exp upgrades don't actually affect all the characters at the same rate. it's not noticeable till late game, but eventually the first character out-spans the rest of them by a lot.
there seems to be a bug where the metal detector will check out the first squares, then the game levels down because all items are grabbed -- despite the first square having one
