Good game! The graphics are cute, especially the main character. I think the overall mechanic of the game is quite complex and can lead to some very in-depth gameplay. But this can also be a crutch if not introduced correctly to the player.
If you plan on developing the game further, it would be good to introduce the mechanics to the player in easy to digest levels. The signs that give you hints should also be compulsory to look at. Currently they're easy to dismiss.
UI to indicated how many fountains are left is also definitely needed.
Overall great work! I noticed that the player character sits down when idle for 10+ seconds. I like small touches like this.
