Nice concept and gameplay. But I found some frustrating things.
The first time I played I found no objective, lost interest and leaved it. I played again because I read in the 'Medals' that I could see some things like moon and aliens.
What is very frustrating is that I wasted many diamonds just buying things like accesories and the 'Item Preview' that does nothing necessary to achieve the moon. Buying things like those just delayed unncessesarily the objective of reaching the moon. The apples should be used to buy those fancy items, not the so hard to collect diamonds.
The 'Running Time Medal' is like a petition to play this game for at least an hour.
1 star because the concept is very good. But it is not very friendly to first players that doesn't understand the rules.
