Story:
The story of the game isn't really there. It starts with a king getting kidnapped and you, a little girl has to safe him and defeat the dark lord. There's almost no story, just at the end you see a few scenes.
Gameplay:
Magical Pop'n is a jump'n'run with typical jump passages and some magic skills you get. You go from one stage to the other, find new skills, heart pieces and beat some enemies. Within the stages you've got different ways to get through and find things. Because of the skills the game has a nice feature and a good flow. The enemies are not very hard just like the bosses. Even the jump passages aren't that difficult.
Graphic/Stages:
The graphic of the game is very good, you've got well animated characters. The stages are nice and some of them look good (posted screenshot) but they are not really special.
Sound:
The sound of the game is good and matches very well with the stages and look of the game.
Conclusion:
Magical Pop'n is a good jump'n'run with nice stages and graphics, some cool magic skills and different ways within the stages. Unfortunately it's to easy and has nothing really unique and special.
