Was very interested from the looks of the game, but got quickly frustrated with the demo.
1. (most glaring issue): every movie file you use ingame causing extreme buffering lags on my computer. Like it plays for a few seconds then gets stucks, buffers appearantly and then springs to the next part in the video and it constantly repeats. That made the actual nice animation work a real drag to sit through. While it might be just my hardware, you might take a look in that, because even though my laptop isn't the newest model it shouldn't have any issues running RPG Maker games.
2.: The writing at the start of the game has way too much exposition about terms, history and and your game's lore I don't actually need at that very moment. Depending on how you structure your narrative, the player doesn't have to know right away stuff - the immediate information is enough - especially if everybody involved should already know it. For example, I don't need to know that some Crestlich was seen 20 years ago or the history of some magical armor, because I don't even really know what anything even is yet.
You really have to use more "Show, Don't tell" by either introducing the setting with some short exposition slide show or you just throw the player into things with the most basic information they need.
tl;dr: Your writing relies too much on exposition this early into the game and it feels especially clunky because of it.
Hope this feedback is helpful to you, because I see the effort that went into the game, but atleast for me, it has a real hard time getting me hooked for more.
