Actually, there's pretty much images for every quest in 1 certain navigation menu. It's some (!) you see after a while playing, above the skillbar etc. Pretty noticeable and convinient.
It seems like it's not all too hard to level up either. Though that's where most MMOs are heading nowdays.
Actually, they're heading towards those C9, MabinogiHeroes kind of games, but it's still good to see these kind of games around, since they're adorable.
This game is the equivelant of Cute-em-up in the shmup genre.
EDIT: Also, did I mention there's nearly zero lag?
