Wow, really surprised me with the guitar... cool and unexpected! Also the very airy and ethereal synths contrast nicely against the really dirty bit-crushy drums. Felt like the second section between :30 and 1:30 could've been half as long, or had some variation on the second repeat. Cool crazy breakdown in the middle, though it felt out of place to the rest of the piece. Like it was lifted from a different song. The ending seemed a bit tacked on, like you weren't sure what else to do. I think it would be better if you could find a smoother transition into the guitar repeating at the end. But as you said, just tinkering... definitely some cool ideas here. =)

Some ideas, just tinkering
