Starbound - Game UI Design

This is a game concept I've been working on for some time. The basic idea is that you go exploring galaxies and colonizing different planets, ultimately taking over the entire universe.

You start off with one space ship but then you collect credits to buy upgrades and other ships. There will be in-app purchases to buy credit packs and access to special items and other galaxies.

The video attached was taken right out of the game engine (Unity3D) and the full (rough) concept is attached.

One thing to keep in mind is that 90% of this concept was built and optimized for the game engine and everything is low poly, which explains the loss of quality but it's just how it needs to be to run on iPhone/iPad.

Feedback and other ideas welcome!
