Finally an idol game that have a simple gameplay and easy leveling up cards. I've played all kinds of game like this but none of them was really quite simple like this one. The characters are good, the design is cute, the sound and music is pretty good too (the BGM for the lesson is making me sleepy whenever I play it xD)
It's funny though that they using a "Dream" concept in this game, but I still like it.
Love the atmosphere, love the simpleness, love it all.
