I really liked the art style!
Unfortunately though, I couldn't understand the gameplay. Only managed to obtain somehow some objects and sell some of them.
Couldn't understand why they weren't accepting the price, as I set all of them to 0, or of a minimum of 5.
And why the left slot have a separation from the right ones?
And I think the dialogue at the start was a bit long, maybe you could make a guided tutorial while the dialogue goes forward so that the player understands the game and the story in the meantime.
