[Suggestion] Game example?

[rubyFeedback]

Hey there,

I know you are probably very busy, but would you consider adding a simple game example for
azul, and add a screenshot or two on the main page? Just to demo a bit what one can do via
azul.

Two examples that come to mind are snake (the game) and tetris. An example for tetris
can be seen by the glimmer libui dsl here:

I am thinking of something similar to azul, but if it is too much work then perhaps the snake
game, which should be quite simple to do.
