Click to +1, click to +1, click to +1, repeat a few thousand times, then you have completed the game! It's so boring, you will not know when you have landed on the moon, you will not know when you have completed the game, it's just clicking from one screen to the next over and over again. There is no way to fail, there is no meaningful decisions to make, and there is no story of any kind. The game design is basically every mobile phone cash grab ever made with a different theme and a different skin, release a game every 3 months, rinse and repeat. If you've played one you've played them all.
