About Lullaby Days

● NOTICE ●

  • The game is not easy. Spinel's 'help' in the game is different when the egg/duckling/girl period, it will be a reference for the progress of the game.
  • Some endings contain horror productions, so people with weak mind and body need to be careful.


Game operation


All operations are possible with mouse. However, some operations support keyboard, so it is convenient to mix them. Please refer to the 'Help' inside the game.
The most important 'fast progress' is the keyboard left Ctrl or Shift button or right-click of the mouse. 'Window Mode' is keyboard Alt + Enter.

Daughter who grows from egg to duckling to human form


The first thing you will take on is a large egg. Careful care will give birth to a baby duck, and activities as a duckling may help change her daughter's attributes or discover aptitudes. The duckling grows up to be a daughter in human form, who ends up spending her 13th, 15th, and 17th years old with you.

Flexible growth system


Rather than filling the period, it is a system in which a daughter grows when a certain amount of mana is filled. So, if you want to see the ending quickly, you don't have to spend the entire given period, you can grow the daughter any time you want. So, simple endings that require low stats can be viewed quickly, and advanced endings that require more effort take longer, so the playtime per run is flexible.
In addition, the more you watch the ending, the more Swan Topaz is strengthened , and as more episodes are added, it becomes easier to grow your daughter. Help her become a hero by fortifying Swantopaz to its final form.

Education, exploration system


The daughter will be educated, work, and read book according to your schedule. Depending on her age, abilities, etc., the kind of activities getting increase. In the daily life, she will make friends or share her dreams with people.

Exploration around the lake is a side-scrolling RPG that is easy to operate. As long as she supports her stamina, she can continue exploring for several days, so this system has high degree of freedom, and there are many events. During the exploration, you can get items or gain combat experience by fighting monsters.

Festival and competition system


Various contests are held on certain days to win prizes or gain reputation. There are martial arts competitions with tournament battles, and sword dance and chant competitions with mini-games to determine victory and defeat. Your daughter can also spend time with her friends by participating in the festival.

Friendly with daughter through dialogue


Your daughter will follow you well generally, but it's a good idea to usualy conversation with her as leaving her unattended for a long time will make you less credible. She will talk about a variety of topics, including aptitudes, part-time jobs, friends, and more. Please take a look at her condition through conversation.

A main story that transcends time and space


\Lullaby Days\ has \70 kinds of endings\ that differ depending on the daughter’s ability, attribute, event, etc., and the game starts over from the beginning when you see the ending. However, each round of the game is not independent, and there is a main storyline that connects to each other. Will you ever be able to defeat the Demon Lord and save the kingdom? Only when the conditions are satisfied can the true ending be reached.

A side story with love and friendship


About 90 characters appear in \Lullaby Days \, and if you make a relationship with a specific character and satisfy the conditions, there are also endings such as accomplish the dream together or becoming a lover.

Lullaby Days is a whimsical and heartfelt life simulation game developed and published by Sunflo Labs that draws clear inspiration from classic “raising sims” like Princess Maker while infusing the genre with its own eccentric fantasy charm. The story begins with an endearing twist—you are entrusted with an egg that, once hatched, reveals a duckling girl destined to grow into a human hero. From this point, the player’s task is to nurture, educate, and guide her as she matures, shaping her personality, abilities, and future through hundreds of small choices. The setting, the kingdom of Oberebach, serves as both a home and a stage for her growth, filled with colorful townspeople, magical creatures, and opportunities for adventure. What sets Lullaby Days apart is its combination of nurturing simulation, light combat, and exploration, presented with an almost fairy-tale innocence that makes the experience feel simultaneously nostalgic and fresh. The heart of the game lies in its daily schedule system, where you assign activities that influence your daughter’s development. She can study, take part-time jobs, explore the wilderness, train for tournaments, or rest to recover her stamina.…

This game is PAIN!!! Its EXTREMELY poorly balanced and cryptic! I LOVE this game but the combat system is VERY unfair and challenging! They will make your 20 day old daughter go up against enemies that get 3-4 turns in a row and do HUNDREDS of damage! It has so many endings and I don't understand how anything works and am constantly learning new things and how to find hidden jobs and learning how unexplained things work! This is one of the funniest bad games I have played in a while. The writing is funny and cute and the story is adorable! The art is decent and I love all the outfits and discovering new ending always feels fun! I recommend this game if you like frustrating management sims with cryptic mechanics and extremely unforgiving gameplay and watching your daughter disappoint you (or you failing as a parent)!

Not a bad game... just never out of debt? My duck will forever work and never be paid for work... making it impossible to afford classes... so I'm confused if that's a glitch or if that is the actual game?
Not recommended Aug 21, 2023
poorly drawn, poorly translated, and just lazy achievements and buggy stuff. also don't drink mana potions, they will crash your game.
