Nice game here, got some old atari vibes. I liked that you added a boss battle too. The house smashing sound effect felt out of place, and though jumping on houses started as fun I wish you had done more to it. Maybe houses that required you to slam down on them, or houses that required you to charge up a beam of some sort? With more levels to the gameplay this could be a very good game, though that's not to say it isn't already fun to play.
