Fun rhythm and good use of staccato. The funky piano part around 1:00 made me smile. I definitely feel the tension rising toward the last third of the loop as the guitar gets more chromatic. IMO, it's tricky to picture this on a loop since the song evolves a lot over its duration. The gradual changes are all coherent from A to B to C to D, but there's some built-up intensity that the transition from D to A abandons. If I used this, I could see myself treating it as two independent looping songs using 1:25 as the split, where maybe the first part would be the approach toward an encounter and the latter part would be for actively engaging that foe. Whatever the format, this is good stuff.
