This is a cute little game. It's pretty basic but not unfun. I'd call this more of a clicker game than a traditional virtual pet game. 

The basic mechanic of clicking the fire hydrant and the chests is fun enough. It would be nice to see a little more characterization to the fire hydrant. I think bizarre virtual pet games where you have to create a bond with a strange object are interesting but they're usually made by the ways you take care of the inanimate object. Like if you could spend gold to improve the living quarters or add accessories to the hydrant might be nice.
