Great game! Fun gameplay and concept that has a ton of potential. Takes the 2048 concept and applies it to a conventional puzzler. I got stumped multiple times and it was extremely satisfying when I finally solved them.
Now, as a composition major: Music-wise, I think it works well with the gameplay! But if I'm being extremely picky and constructive, I'd recommend looking into mastering and general mixing techniques to further improve your music. (Again it works, this is just being extremely picky; I think it's good!), the bass was a bit too much and muddy, the drums could be loads louder, and there wasn't much high end to my tastes (the lead felt too soft and muddy as well). Hope that helps!
