Enjoyed this one a lot! Be great if there were other songs with more elements but overall this is a great concept.
I only wish there were in game instructions as (stupidly, admittedly) I didn't think to click when the sound was at its loudest.
It could even have been nice to be have the ability to click when the instrument was at my preferred mixing taste (bit muso). I also got stuck after discovering the keyboard, frantically searching for a guitar that I was uncertain as to whether it existed.
