Memento choosing and more

I've added a bunch of stuff today

- Now when getting a memento you'll have to choose one of two of them
- Running speed a bit buffed on zero stamina
- Option to get back to the main menu
- Also added a credits list with funny logo of our little team
- Reworked the main menu a little bit
