Lunar Rush was made in Unity during a 3 day game jam, by me and two others.
The theme we were given for our game was 'Lunar' and the restriction that we had to incorporate in to the game was '10 seconds'.

In Lunar Rush, the player's goal is to collect all of the stars within each level and transport them back to their ship. The player begins with an oxygen tank that provides them with 10 seconds of oxygen. If the player runs out of oxygen, the level ends, and they must try again. To survive, the player must locate additional oxygen tanks scattered throughout the levels.
