Tip: Switch palace switches normally disappear if you replay the level. However, if you insert them as direct Map16 and use the hex-edit at $00EEB2 in the ROM map, you can replay the level without a problem.
The tempo is a tad bit fast. The echo could be better too, in fact you could match it up exactly like the originals and give the echo volume $5D $5D to match it up as well as put the FIR coefficients in. The @1 at the beginning is too loud and should be dialed down. Nice work nonetheless!
