Great energy, great progression, and just amazing melody all together! I think the challenge you described is a really cool idea, so the result of your experiment being so awesome sounding I'd say is a total success. You make use of so many things in such an awesome way, especially the gates at the end to kinda slow the song and end it. And in general I'm a huge fan of how the song keeps evolving from start to finish, it never stagnates or gets repetitive and feels like a fun and crazy journey. Awesome work once again, keep it up!!
