This is a fun action game. The combination of otherworldliness and suburbia reminds me of Earthbound, or Zombies Ate My Neighbors. Nice music, very good sound effects. Most of the graphics are very attractive.
One graphical quibble: The player sprite doesn't really match the rest of the art, which is more high-resolution.
Also, I think it would have made sense to be able to: (a) suck up coins with the vacuum cleaner, and (b) spend coins at vending machines.
