Lucky Star Moe Drill - NDS

Lucky Star Moe Drill


Has anyone played this game?

The game is basically a bunch of homework drills that lets you play as a few different characters ( mostly the main ones, like Konata, Tsukasa, ETC.)
You mostly do basic math problems to win the game, but sometimes you would do some type of memory drill (?? I'm no good with japanese text ??)
It sounds like a dull game, but it is actually really fun.

Had anyone else played this? What do you think of it?
