Enjoyment to the max! I know how you feel, I am currently working on a song myself and I have been switching so much stuff around and I still cant figure out how to make some parts sound the way I want them to sound. The melodies themselves are great but I havent still figured out the right pattern for them but lets talk more about your song haha. I think you did a great job on combining diffent elements together being the robot sounds and the guitar and the melody is quite catchy too. I think its perfect for the game its used for. :)
