Hey your game looks nice, and I like shenanigans based brawl games, but as I am a lonely cave dweller and have 1 controller I couldn't really play the game, but a gave it a test. I looks fun to play, some things to take note:
The barrel (and I think the chair) can get stuck in the piano, I can't retrieve it by any sides.
When you stand really close to the opponent you miss him because the object only has collision after a bit.
But as far as I know construct 3 is pain to work so kudos to you for making a game with it.
I felt a bit let down as I was expecting some hardbass as the video sugested, but the music you choose for the game is nice, maybe a cut in the end could be nice so it looped better.
