Manaphore

Amidst a mana shortage crisis in the kingdom of Fantastica, for the topic of your thesis in order to claim the coveted Gold Rank of the Academy, you chose the creation of life. Specifically, a project to create lifeforms made out of magic that consume mana to produce more in return. Your attempt at the creation of life is successful, giving it the name of Manaphore.
In this experiment, using your own household as testing grounds, you will learn that Manaphore has produced offspring of its own, the Manaspawn, and how they all behave. Where shall this experiment take you in the end, and what surprises will it show you when they begin to evolve?
Gameplay
Before starting each night, you have nigh-total control over the Manaspawn's activity. Spend mana to feed and grow them and get more in return at the end of the night! Then, you can use that produced mana to improve your means of defense! As the Manaspawn grow, they will begin to evolve. They will change their behavior, become more active, and even gain new abilities. However...

...when the clock hits midnight, the Manaspawn will come for you. But metal doors and cameras, let alone electricity, haven't been invented in your home nation, and wooden doors won't cut it!
Use a Crystal Ball to observe the Manaspawn, wield the power of the elements to ward them off with elemental walls and other artifacts, and call your Familiars to assist in your safety until daybreak at 6 AM! After that, you can harvest the mana they produced during the night! Just be careful to not run out mana at any point!

Key Features
Six Manaspawn to discover, die to, and learn about over the course of six nights! Surely, it won't go wrong at some point, right?

Four Familiars to assist in your night! Use them to repair Watch Crystals, stun the Manaspawn, alter their temperatures, and more...
