a minor thing I found out is that if you don't push the boulder you can go back to the swamp & if you knock on the door the spider fight again re-triggers, I discovered this while thinking about how you sometimes add secret loot usually after completing an area.
I thought about how this could be used to grind exp, but I ended up having to pay the guild staff member twice.
I don't feel that this has to be patched as once you push the boulder into the water you can't come back to the swamp.
Also I changed my itch profile to the image of Shida blushing ♡.
P.S. I don't know if I cropped the image well 😅
