I like the take on the word "score", and liked how the higher the "warmth" the more instruments came in. It was a nice touch. The art is pretty good too.
My only issue probably is with the easy difficulty. The notes were kinda hard to track as they didn't stand out enough, and the timings were just a tad bit un forgiving (especially if I timed switching color and note pressed at the same time), but that would be nitpicking a bit given the time limit we had. Still great execution given the constraints.
Overall, had a lot of fun with this.
