All of us started where you are now. We wanted to create something. Something small and easy, which seems accomplishable. Then we started coding, trying out things and looking up stuff. We all took hours for the first few lines of code we wrote on our own!
So let me congratulate you: You managed to take the first step to becoming awesome! All you need to focus on now is to not settle. Add features to your little game, think off a new challenge (maybe even a new game?)! Keep programming and having fun. No one will jugde your time, because as you go, you will learn and practice. The more you learn and practice, the faster you get.
Heck, before you even realize it, a thousand lines is what you write for breakfast :D
---> On a more advanced note: Do not measure your code or your coding performance based on lines of code or the time needed to write them. Many problems require you to think and come up with a good solution. A good solution might be as short as a few lines and take hours of thinking, but will beat everything else ;)
