This is great! Short, sweet, and to the point. I tried the first level a few times before realizing how to smash the golden toilet. Well done!
I was excited to read that you recorded all the sound effects by smashing things in your garage. They felt a little repetitive, but they were very satisfying when breaking down huge tables and racks of objects. I hope you didn't actually smash a guitar, though!
I think you could be a little more explicit about being able to smash through a door. I lost my first run because I got stuck in the alley. Just moving the instructions to smash next to the door with an arrow would do it. But really, I don't have much to suggest for improvement. You set up the premise and deliver on it quickly and there's just enough to not let it overstay its welcome. And there's a lot you could do with this idea if you wanted to take it further.
Great job and an excellent jam game. This is the type of game that I love playing in a jam. Congrats :)
