Yoshi's Island is still just as good, with beautiful visuals and new features and levels.
Graphics: 10/10
Beautiful crayon-inspired visuals. The backgrounds look like drawings right from a children's storybook. All the different grounds are lush and colorful, the enemies are cute, and the environments are just great. Birds are flying around, the sun is setting, the forest is full of critters, and caves are filled with crystals, fungi, and strange plants.
Sounds: 9/10
Yoshi's makes cute little baby sounds and goes "Rrrrrrr" when he's fluttering. The Shy Guys go "Heave, ho" and the birds tweet. It's all very adorable. Baby Mario's crying, however, gets on my nerves.
Music: 8/10
All the great, catchy music you remember from the SNES game. It would have been nice to have had some new music, too, but I guess it's okay.
Gameplay: 10/10
The platforming and puzzles are just as fun as ever. Yoshi uses his egg throwing abilities in unique challenges and puzzles. Every level is very creative.
Level Design: 10/10
Every level presents a unique challenge. "Marching Milde's Fort" requires you to hunt down four keys in four special, deadly rooms: Lava, Spikes/Bandits, Spike Plants, and Spike Runners. "Poochy Ain't Stupid" has you ride a hyperactive dog across a cave flooded with lava. "Chomp Rock Zone" has you roll a stone ball around the level, using it to reach special areas. "Hit that Switch!" requires you to stomp a series of switches while racing through the level before they wear off.
The GBA game comes with six all new levels not found in the SNES version. These levels, called "Secrets," are insanely difficult masterpieces, full of enemies, hazards, and mile-wide pits.
Replay Value: 10/10
These levels are so cool and fun, you'll want to play them over and over again. However, the ultimate goal in Yoshi's Island is to collect every single item (100 pts) in every single level. This is an unbelievably hard task that you will spend hours trying to accomplish.
In conclusion, this is game is pretty much perfect, full of awesome content and fun playing. Anyone who missed out on the SNES classic should undubitably get this game. This is the must-have GBA game.
