You'll probably be happy to hear I'm currently working on a sequel. It's admittedly changing some things up, but I'll say this: A lot of it is an attempt to address the flaw that learning all the attacks is basically the end of the game, and other things like that which I've had pointed out to me.
I've... had a lot of time to think about how to attempt to solve all that. So hopefully it'll actually work out, heh.
