Oh my...! I'd actually considered a game like this recently. While I'm aiming for a sci-fantasy right now, it's awesome to see this. If it worked for Glory of Heracles in Japan (up till the DS game), why not for RPG Maker?
I promised I'd play and review a lot of games before. I still need to, but for what it's worth, this is on the queue. :D
Well, don't get your hopes up. It's only five minutes long and there's only one battle in it. But I do hope you enjoy it!
