It took me a while to figure out the controls, but I did eventually... quite intuitive! It's a good start, I bet that if you had more time to dedicate to this game something great could be done. A tip that I can give you is when you lack the time, don't be afraid to use free assets, they help a lot to do better concepts when we're in a hurry. Also there was some things that you could have done that don't take too much times and can add a lot to the experience, like putting music and sound effects... it can be done in less than 30 seconds. Anyway, at least you made an effort to deliver it and participate, even with life and job getting in the way, also the concept of a sports game in space is really good, I know that if you work hard from now on, you can make something out of it! Hope to see more from you in the future :)
