While the gameplay was lacking (sorry about the time), the story was very intriguing, and I wanted more after reaching the end. I'm impressed how much you got done in such a short amount of time.
Towards the end, I wasn't quite sure which world was the original one, so maybe a way to indicate that (GUI element or having the worlds have distinct visuals?).
I don't know the limits of RPG Maker or your game making skills, but it'd be cool to see the linked world mechanic extend into the battles as well, like how Cris Tales does it.
Overall, not bad.
