I can only guess the idea and in my head it's really interesting. You blow your enemies off the map with your trumpet. I don't really see it working in the game. I don't get any feedback if my trumpet actually pushes enemies away from me. Also there is no audio of the trumpet in the game about trumpets!

The range on the attack is a bit short, and you're right there's not that much visual feedback. I think it's a bit more obvious once you've tried it for a bit longer (try go really close to an enemy and attack) or if you try it in multiplayer (if you plug in 1 or more controllers it enables split screen, which was the main focus).
I was going to add audio for the trumpets (as well as different attack types like strong and weak) but something came up so I had to reprioritise and get the main game loop working before submission.
Thanks for the feedback!
