Currently there is no demo or a trailer, but I'll try to arrange something on your request.
Thanks! I was wondering if it's an RPG, or an adventure, or a mix of both... If it has combat (TB, real-time?)... :)
The game's engine is RPG Maker 2003, so the overworld and the combat system are very similar to JRPGs like Final Fantasy 2 or indie games like Space Funeral and OFF.
