The song was great, I liked all of it. The beginning was good, but I feel like the silence in 0:13 is too long. Maybe making it a second shorter would be a good idea. It's just my opinion though.
During the song, I found some moments where it felt a little repetitive. It wasn't through all the song, only a few moments, but overall I you added some variation which is good. Also, Tetris at 0:28. I wonder if you really thought about it while you were making it, but I liked that part (which is also repeated later).
I also liked the ending, and the way it got slower when it was finishing, it was a good way to finish the song.
My score is 5/5 and 9/10. Good work!
