Decent game, sequel is mediocre. It can be quite a tedious grind... and the humor is pretty bad.
It's actually not too tedious to grind if you know WHERE to do it.
Once I got to 5-3, I passed the triple exp bill (and apparently must do this repeatedly, which is the one tedious part), threw all the monsters into one, and then put that one in the non-invincibility panel. Bam: from level 22 to level 38 in about 10 minutes (including the bill and the map and such).
... and why does everyone keep bashing the humor? T_T
