It's just fun to go around eating stuff, art and music are sweet, satisfying progression, great puzzle design, crazy endings and secrets. Just play it.

This is a game that has good pixel art charm that delivers quite nicely in a game similar to old Zelda games. You travel the land as a juvenile black hole with a questionable appetite (at least Kirby knows what's edible) trying to stop some random evil king who wants to hoard all the food (which makes it kinda hypocritical now that I'm writing it out) by barfing out whatever you can shove into that mouth of his. Its a more fleshed out version of its origin game "Buffet Knight" and is decent for what it is. I wouldn't say its worth it but if you like games similar to Zelda and Kirby, knock yourself out.
