I want to start off by thanking Sam and Silviera. The time you took to review EthD really means a lot to me, and I've taken what you've said and am trying to improve on EthD's weak spots.
In honor of Release Something IX, I have assembled an early preview of the future revamp tech demo. In this quick little demo, you can explore one room, and fight one battle as much as you like. This by no means a complete build--there's no menu beyond the root one--but the focus is on lead character switching and the basics of the battle system, even if I haven't played with damage algorithms or the stats I have to add yet. Please don't mind the temporary rtp for battle animations and sounds, those will most likely be replaced before the full tech demo.
The plan for the future is to have the tech demo show absolutely everything the game will have to offer in terms of systems and base gameplay. Currently I don't plan to release any other demos, since I think a remake of 2.0 with the new systems would be redundant. Also, I might blog on the specifics of the battle system if people are interested. For now, feel free to ask any questions and I'll do my best to answer.
