It actually have a 2 mode of playing it
since I play this until the game is erroring itself... I mean... the sprite... is gone for sure...

on the menu, if you tap on the chibi chara on the bottom right, and the chibi chara using a glasses that means you can access the second mode that you play with the girl... with her glasses...

the CG itself is same... I'm still desperate what the hell is this game called... I mean... the CG definitely not officially for DS ya?
