The Untitled Space Game

Hi guys, this is the first game i develop in Unity. I am a spanish rookie developer who is learning to program in unity and this is my first game. I know it has many bugs as this is the first game that I make by myself and it has had 2 weeks of development (more or less), it is appreciated that sixteen feedback on the game to improve in the future. Enjoy my game and the instructions are inside the game ^^.
