Is this an upgraded version of the game that was part of the Megallenium game pack?
This is more like a sequel. It's 5x bigger with 5x more stuff to collect. It's got new graphics, new systems, and lots more stuff to do. Basically, it's like the original, but way more awesome.
Am I convincing you?
You are, yes. c.c
Xoo was my favorite of the pack, anyway, so it would catch my interest one way or another.
Now, crossing my fingers for Dr. Moonlight's Happyworld. XD
