Yoshi's Island is without a doubt the best looking game on the SNES. The visuals are outstanding and adapt an art style that will stand the test of time, utilizing a lot of really smart techniques to even incorporate some "3D" visuals. The music is as good as Mario games can get, with a wonderful touch of adding elements to the main map theme with every new world. Gameplay incorporates a lot of unique elements like storing, aiming, and throwing eggs as well as power-ups like the horrific helicopter.

However, I cannot in good conscience give a perfect rating to a game that punishes you for taking damage with loud beeping and literal baby crying. It is one of the most bafflingly poor game design decisions to ever come out of Nintendo games. Yoshi's Island is a firm 4/5.
