I mean, it's functional, finished and it's all done in Scratch, which makes the achievement about 10 times more impressive. There isn't really any rhythm, or music and well, the visuals are very basic.... but we all have to start somewhere. It's not a masterpiece, but keep at it, keep learning and improving your skills and soon enough you'll get people looking up to you :) Take it from me, I've been drawing levels for Portal 2 when I was 10, now I'm studying game design at a university. Don't give up, maybe give Unity a shot, it's going to be hard at first, but you can make so, so much more in a proper game engine! Good luck :)
