Thank you for your feedback !! <3 You're not the first to tell me that they want to play the mermaid ^^
Basically, my plan was that once all the water items where collected and the fountain reactivated, rain would fall and the water would begin to rise, and all the animals calm down. Like a second part of the game.
And indeed, the use of water vision is missing a restriction ! Do you have an idea ? :) Perhaps it could only be accessible once an action is performed (defeat an enemy (but I don't have a fight system lol), find an item) or accessible in limited time or resources...
Also agree about the music throughout the game :)
