Add tutorial / game explanation

[fry-]

For new players, it is important to get the basic idea of the game. Some minimal "tutorial" would be great. It could be like this, but you can come up with your own idea:

• Starts on first app start, then sets a flag in the code that it was viewed already so it doesn't comes up on future starts
• Has a button in the menu to re-view the tutorial

content:

• shows a screenshot with all the major parts of the game, with text on every part to explain it (obstacles, player, color switcher)
• has a button to close the tutorial

Hmm, I think only a small text could be enough, since the game mechanics aren't that complicated.

Sure, whatever is enough 👍 I don't want to go too fancy on this one anyways, its of lesser importance

Anyone up for writing the explanation text with optional small screenshot explaning dimensions ?
