So, having played Undertale and thoroughly enjoyed it, I latched upon an idea of having a similar style to the game. The thing is, I am coming from a different place than Undertale, so it was less an absolute pacifist game and at best, a boss only run.

The game mechanics involves donating items, similar to how offering meat to the critter in Zelda 1 (or food in BotW) distracts the critter. The battle does not count as a victory (kill) and you may or may not get many items, but you earn exp and gold. Besides avoiding bad endings, certain enemies have karma attacks, which can be devastating if you went kill crazy. Also, Ambrosia's Tao command is most effective when your karma is unstained as too much bad karma makes it backfire.

This requires large amounts of fishing, mining, and/or stealing and selling, but it's kinda cool to just bribe some critter off with huge amounts of fish or something. I might tone down the amounts later, but anyway.
