Thanks for playing! If you do do another run, you can make it to Spiriton to the south without fighting anything (might need to save and reload a few times to get the timing down...), so buying too many spoons should never be a problem ;). Also, you can sell them back at cost.
Sadly I can't take credit for the characters though, those were mostly part of an existing, pretty great, asset pack (details linked on the game page), all I did was some palette swaps there ^_^.
