I have an idea!!!
I think that creatures and objects should have sounds of their own outside that they already have some.
As an example, snowjump will have the sound of a spring, the slawblade will have its sound, mr_tree will perhaps have the sound of leaves as an idea. The tux could be heard in his footsteps. The cannons make a gunshot sound (this made us feel the shot, and this prevented it).
I think that would make the game better.
