Excellent Puzzler.
Both the soundtrack and effects,are pleasing to listen to.The soundtrack is composed of three different versions like most Gameboy games,each being either sped up,slowed down,or in its regular glory.The whole game looks/sounds great.
The game play has to be great for a puzzle game to be,fun of course,and Yoshi's Cookie is fun.The game is very simple.At the start of each stage,your given a bunch of different cookies,with these cookies,you must place all cookies of the same type in the same row for those cookies to dissolve away.The controls work well,and you can easily manipulate each cookie.It can become pretty challenging because the game constantly adds more cookies to your already large group of cookies.Though,the game is pretty unique,but it still involves the classic,put these things in a row to make them go away theme.
Final Verdict:Yoshi's Cookie ranks high among the Gameboy's best puzzle games,and one you should definitely look into.
