If you're writing paragraph long instructions (as seen in the picture of your machine), you've probably designed your game wrong. In fact these days if you have instructions at all, you're probably doing it wrong.

Its not about how obvious you think it is, its about how hard it seems to the user. And the harder you make it the fewer users you'll have.

Secondarily, you put your instructions in printed form next to the screen -- when all the user cares about is the screen itself.
