In this game, you flash back and forth between two different times; yesterday, when you were a Stellar Girl, and now as a mundane human.
The game is mostly choosing the order of four options, moving to a new scene, and repeating. I found myself eager to know what happened the day before. I found the game exciting.
However, I didn't feel strongly connected to the protagonist, and I felt satisfied with my first playthrough without exploring more options.
