Yoshi's Island is by far my favorite SNES game. Naval Piranha was actually a boss that used to give me some troubles when I was younger. I remember my cousin showing me that little technique on beating him before the battle even starts and my mind was blown. This sounds almost identical to the original yet sounds somewhat more energetic somehow. I can't really explain it. But once again, you hit the nail right on the coffin. This was done very well.

this would be my favorite boss theme from the mario games i've played (not counting in the 3ds new yoshi's island boss theme, i hate the whole damn thing because music is important to me in games and when i hear any song from the game, it reminds me of how good they were on the snes version) and you gave it a nice addon by including the battle theme from tetris attack too

El intro estuvo de huevos! Esta tenso y tiene una onda medio Rave que me encanto! El platillo que metiste en el segundo 24 le da una intensidad muy agradable pero el platillo que esta por ahi del segundo 31 esta o fuera de tiempo o algo pasa ahi que se desfasa un poco. The drums are really good. I love how hard the snare sounds. The Tetris Attack Battle theme caught me off guard but by the end of it when it mixes with the Naval Piranha theme it fit perfectly.
Estas rolas noventeras estan llenas de nostalgia para mi , en especial la batalla con la Naval Piranha. Le has dado vida nueva y por momentos incluso podría pensar que esta cancion hubiera quedado bien en Mortal Kombat o Killer Instinct por toda la energia que le diste.
The only thing I would recommend is more low end in the mix. Maybe with a stronger bass synth or something because while the kick is great, you could really fill your mix out more with more bass like during the Tetris part....but more.

Vas mejorando mi estimado Volkov!
