Hmm, that game had some great stuff in it. I was just reminded of my Spell Checker, a black checker you could cast a spell into (spells were Enchanted Forest Chronicles-style rhymes) to see what it would do and how well. And, of course, there's a very useful (to certain people) magic item in Boreala that comes from Bobby and Bonnie.
Actually, it sorta reminds me of Minus. I guess omnipotence doesn't get boring if you're a kid? I do like the idea of a pantheon with a "most powerful" god that's a Minus-like kid and thus doesn't participate properly in the struggles of the other gods, though I'm sure things like that have been done before.
P.S. I hadn't seen this other comic by the Minus girl* before, but I'm a sucker for things that're very Japan, and I also like the handling of invisibility/ghostishness: Socks.
*: Yes, he's actually a guy, though I didn't know that 'til I checked. I'm tempted to start using girl gender-neutrally for the power of awesome and to confuse feminists, but I'm not sure I'm girl enough. Or something like that.
