Very nice concept! I like how the world around you changes to the rhythm of the music. The song as well was very nice with easy cues to know when the platforms would change. This game has a lot of potential and I can't wait to see what you come up with in the future :D
I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
