Take a look at Remnant as of GGJ '17. This version was completed in about 5 days (some time was taken before the game jam to set up menu navigation) by Jared Hill and myself.
In the game, we use some icon assets from various publishers on FlatIcon along with some music productions from Newgrounds. All programming, UI/UX design, and gameplay design has been done by our little two-man team. My contribution consisted of menu navigation, UI/UX design, and effects for the space nebula and gravity wells.
Since the game jam, we have been actively working on completing the full version, which includes 40 levels across 8 galaxies, a multitude of ships, Google Play integration, and more. We aim to be done with the Android and iOS versions by the end of February 2017.
