The Mall is a short visual novel about Yuna and her sister Yumi. 

What starts as a simple trip to buy clothes turns surreal when Yuna steps into the bathroom—and comes out to find Yumi missing. Her search leads her deeper into the mall’s strange logic, until she finds herself on a dark train with someone who seems to know more than they should. Together, they try to escape, but the mall remembers more than it lets on.

There are three endings in total, and one little secret dialogue!...That doesn't really contribute to the lore or anything, but I just thought it'd be silly... 😛
