Lost Magic has some charm, but it is too full of annoyances and frustration to be highly recommended.
GAMEPLAY is fair. The stylus is used at all times in order to command Isaac (the main character) and his monsters. The stylus is also used to draw the many spells in the game.
Unfortunately, this simple task can become frustrating because Isaac will constantly be drained of MP leaving him defenseless. Too add more annoyance, the poor AI of Isaac's monsters will blindly follow enemies into hot lava pits or run into a horde of enemies only to be slaughtered.
Some of these control issues could easily be solved by adding shortcut commands assigned to any of the A,B,X,Y buttons that would allow for creating groups and giving them battle commands like "wait, follow me, or attack."
Furthermore, the ridiculously difficult time limits and powerful bosses make this a challenging, but not very fun game.
GRAPHICS aren't the best. This game looks more like a GBA game rather than a DS. There is nothing really impressive looking about this game except for maybe a few of the spells.
SOUND is okay. The game has decent music, but is full of annoying sound effects. Especially when trying to connect for Wi-Fi duels. The constant Beep Beep will have players muting the game until the battle starts.
VALUE is good and probably the best thing about it. It will take some time to finish the game since retrying is inevitable. The Wi-Fi duel is fun enough, but random Wi-Fi battles aren't chosen accordingly because your opponent's level isn't necessary anywhere near yours.
OVERALL, Lost Magic is just too full of annoyances and frustration to be highly recommended. There is some fun to be had, but this game isn't for everyone. Rent it before you buy it.
