Epic is used too much, so I'll just say godly.
This is certainly a grand achievement amongst the use of Flash. It's an amazing RPG. I can't even begin to imagine how much coding had to go into it. It brings me to tears thinking about the painstaking effort. I've worked with pre-built engines like RPGmaker and Game-maker before, but I can't imagine writing all this coding in Flash.
I wouldn't be surprised if the next version had a world map or townscapes. Though I imagine that if you tried that it might exceed the 10mb limit Newgrounds has set. Too bad, because this is pretty much a game that I could see on the DS or PSP.
Who knows though, mayhaps with a bigger team and some funding you could expand and develop this as a game for either system. I would love to see that. In the meantime, keep up the great work.
Oh yes, one more thing. I also love the mini-games. A beat-em-up side-scroller WITHIN an RPG; brilliant!
