This game is super funny and looks great! I have a few ideas for stuff to add that could make the game even more fun:
Make the throwing feel a little more responsive. It feels kinda floaty, I wanna slam these guys in the face with a vase, or whatever.
Make it so the duck canon can hit their friends so you can bait enemies in front of the duck canon!
Make stuff like the vase break into pieces when you throw it
Render the item you are holding on its own layer so it doesn't go through walls and stuff
Great job!!
