Stumped by a very old game

[Alohana]

Hey Everyone, 

I am trying to get unlimited money in Puzzles and Pixels RPG.  It's a very old game (last updated in 2015), and basically and abandoned beta version.  There is only one currency, and I assumed it would have been easy, but so far I am unable to identify it.  Any one want to try to take a crack at it?  It would be greatly appreciated. I'm guessing it's something simple that I am overlooking, but for the life of me can't figure out what it would be.  Thanks in advance.

Bump: Has anyone been able to crack this?

I've tried fuzzy searches, and unknown variable searches for coin amount

And multiple figures at once for shop items.  But have not been able to find any matching items.
