I am interested in the backstory! And the character designs too! Maybe it is just my dark mind, or the trash actually dead bodies? Because they look like the character we are moving, a round head and a body? And one of the sprites looks like an axe. I apologize if my guesses are wrong.
But I am curious about the background story more, and why other sprites are here, the building itself doesn't seem normal based on the dialogue. Great work!
