Good fun, decent tutorials if a little confusing at times... My main issue is there is no way to pause meaning I often had to restart multiple times before finding the solution which was extremely irritating. I would rather have just chilled and thought about the solution, as your game has a very relaxing feel!! A pause function and maybe a couple different droplet types later on would honestly make this a game I'd be happy to purchase. Good job!
Edit: Forgot to mention that the game is adorable.
