Note - I have no experience in building or monetizing mobile games. Still sharing an idea for problem 2
1. Somewhat similar to Wii, after every X minutes of game play, display a popup with a one minute timer asking users to take a break. to play non stop ask them to buy a premium version.
2. Ask users to pay for higher levels of game maybe ?
