I see the connection to the Kratos mechanic of him tossing the axe and it coming back.
I do like how shooting the boomerang feels, it goes where I would expect it to go. Though it coming back tends to have it dragging on the floor.
Maybe disable the gravity on the boomerang and have it come back. To add onto the gameplay maybe have something that requires the player to mess around with the boomerang coming back? like something hidden behind a wall?
