I play MoF during every full moon as part of my ritual to summon Kanako. Still hasn't worked yet.
If I'm trying to beat IN extra then its about half an hour on the stage and then an hour trying to capture "Fujiyama Volcano"I then rage at the card because I cant capture it or survive it very long and I go play something else.
Ranging from 2-5 hours a day.Well on one occasion it may reach up to 8-12 a day.
1-4 hours on the shmups at most, but I've gone an entire day on IaMP before.
