Hi dinre,
Sorry about the delay! I've been swamped at work with a new position (still getting my bearings). I've uploaded the most recent build (1.40.x) to itch a few days ago, but have yet to post the actual text related to the Pupdate (the changelog). For 1.40.x, that reads as follows:
Ephemeral Tale 1.40.1 Changelog
Fixed a bug where Butter Knife wasn’t properly interacting with the damage system
Fixed a bug where (under a very specific circumstance) Alchemist’s Trick could be exploited
Fixed a bug where legacy saves wouldn’t have the player turn into a mermaid when coming into the Sunken Summit
Fixed a number of passibility issues inside of the Sunken Summit
Rare enemies are now tougher once the player has reached the Realm of Shadows
