Prisma & Avery's Parallel Adventure

Prisma & Avery's Parallel Adventure, also known as Prisma & Avery for short, is an e-shop game for the Nintendo 3DS. It's an action-adventure game that stars the characters created by Daron Nefcy, the creator of the animated series Star Vs the Forces of Evil. This game features original places, characters and enemies designed by Daron herself. Developed by WayForward and animated by Science Saru.

Gameplay
Prisma & Avery will traverse many lands on their journey in a world-overview fashion but with more of a 2-D, 3-D perspective where the horizon (on the opposite side of the screen) is oftentimes visible. Sometimes they will have to jump over danger or pinpoint a northernmost mountain, so this kind of view helps with that. Dungeons are totally overview, even if they're not closed spaces. This helps to know where you and the enemies are.

The game's main catch is its multi-tasking system; as long as the girls are on the same world or are both in Boundaria, the player can switch from one character to the other, wherever her location may be, even if they're inside of a dungeon facing a boss.

Since there aren't tasks that absolutely require a specific girl to get the job done, there is no problem thinking beforehand which of the two heroines needs to explore which area, though there are situations where having Prisma or Avery specifically makes a task easier, like how some "cute" enemies gross the heck out of Avery but not of Prisma, or how Avery can tear down withered trees with her dark bolts, something that Prisma can't and wouldn't want to do.

Finally, there are situations that require BOTH of the girls being together, but usually it's a time when a new world is opened and such, so the girls are likely already together. If not, or when a task becomes too hard for a girl alone, there is the option to teleport one girl to where the other is with the help of a special item.

A two-player option where a friend can control the other girl is also available and the advantages of separating to cover multiple areas stand the same, though this changes and enables other things too.

Story
The game's plot narrates the mishaps of two girls with magic powers (of different sources) as they meet each other, and their adventures in the mysterious all-connecting land of Boundaria as they try to return to their respective homes...
