Starship Parish Design #1

My next game I am working on is a touchscreen game named Starship Parish. Here is a blurb about the game:

Earth has become vast deserts and the need to explore the universe has exploded. With governments only offering limited capacity aboard their ships, people have taken to their own initiative to build and launch themselves to a better world. Workship Parish is one of the staging stations that many explorers first use to start their move for freedom from the wasteland earth. The game starts with you arriving on the Starship Parish and trying to gain your right to head for a new world.
