Astronaut

Hi everyone, heres the first version of my first game I ever made. It´s just a small sidescroller based 2D game, but it took several days to develop. I would appreciate feedback and ideas so that I can improve bugs or bring new content. I know there may are some bugs but before I´ll fix them I want to know if it is worth to improve it.
