Destroy after animation

You don't have it to do this way. You can put most of the code direct in the keyboard events, but this is my way to do it, because I like it clearly arranged and I think it is easier to maintain.

There are several other ways to arrange the code, it's all about personal preferences.

Have you tried the fade out behavior its has a built in destroy you could do is when death animation ends start fade out to destroy. or you could add in a death animation of one frame after death to use for the fade to destroy.
