Raise Your Own Fredrico! is a Tamagotchi-like game. Give him apples to keep his health bar full, but poison to kill him. Customize your Fredrico/Fredrica's gender at the home screen. Try and raise Fredrico/Fredrica to adulthood! Once you're a teenager, two things unlock. One, you can have a pet, but it's completely useless and gets in the way of literally everything, so you really shouldn't. It goes away when you're an adult anyway. Two, you have the option to rob a bank*. Once you're an adult, you can travel to different places, and meet your potential soulmate (to marry them, you have to say "yes", anything else and they'll leave)! Once you've obtained the title "Child Married", wait a bit and you will receive dialogue from your child saying it's time to head home. From there, you can have children and have beat the game (watch for an update where the child can grow up). (*If you rob a bank, you can never travel, get married, or have kids.)
Thanks to Piskel, the sprite making website. Thanks to @redsunboi, @encaticplayz and @cyoteseatoranges for the "say thing with sound #" mechanic. If the music starts to overlap in the game, click the green flag and it should be fine.
