First person you talk to says "let's spar".
This NPC is located within a few tiles of where you start, and doesn't seem particularly formidable, but is too powerful for the main character.
Can kill main character in about 3-4 rounds consistently.
Can't be harmed by main characters attacks of magic.
Escape option is disabled.

Normally, sparring is non-lethal combat, so getting killed in a friendly fight seems a bit off.
I was expecting this to be some sort of training to help newbs, rather than a trap.
I figured the NPC was placed there to somehow join the party, so any interactions I presumed would be beneficial.

A true classic style RPG. Great scenario, amazing soundtracks, I just needed a potion or 2 :), looking forward to see the progress of the game, keep up the good work!

I'll give you a solid three stars, I can tell you haven't developed many games if any at all so I'll give you some advice. You should try to stray away from "This is a demo" especially during the game itself. If you wish to do that either put it in the title or wait until the end of the demo. It's important to have a professional presentation. My other suggestion would be to make custom sprites, tilesets, title screens, and etc if possible. It's hard work but it will pay off in the end if you can do it or find someone else who can. Other than that the animations, sound design, and map design seem to be on the right track. Just keep what I said in mind, I can tell this could be promising in the future.
