I remember the original NES game. I remember stumbling through the game for hours until I finally figured out the point, the haunting 16-bit music, and the last boss (though I never got anywhere close to beating him). Then I heard about this game and was so excited I bought it without reading the reviews.
Remember when your adorable Pikachu evolved into the hideous Richu? This game does that in reverse. It subtracts all the creepy stuff and the mystery of what every bean does, and turns the game into a pure puzzle game. This isn't wholly bad, the puzzles are interesting and the graphics are great fun to look at. The boy is adorable and the blob is joyous. In the old version, the boy was a teenager and the blob looked like tapioca pudding.
My issues with the game is that you have bases (4 in all) and each base has 10 levels. For a bonus, you can try to get every treasure chest, although why they're there is never explained. Too many of the puzzles are spoon-fed to you, where there are little signs that tell you what shape you should make the blob.
My other issues are the jelly beans, themselves. You have an unlimited amount, and you always know what they do. You have a limited selection of beans depending on the level. In the old one, you had every type of bean, not necessarily knowing what they did, and a limited amount. The new style also takes away some of the jokes of the Jelly Beans, like the Coconut Ball and Banana Anvil (say it altogether).
However, these are all nostalgia problems. It is a remake in the most basic sense of the word. But it is also an adorable puzzle game. I highly reccomend it if you're into that stuff. Parents: this is a game that is both thought-provoking and totally innocent. I mean, there's a hug-blob button!
