I wanted to play this version with sprites but I have a mac so I could only play the other demo.
The older demo,( and the older version made with RPGMaker which I also couldn't play, but I watched the video for it), has such strong aesthetics, and I'm sad to see them go. I don't know if this was intentional, but the game has such strong 2000s aesthetics. With the pixelated font and low rez pixelated graphics, and the square profile pic for the characters talking, it all worked together and made me feel like I was playing a game that was created a long time ago, and I loved the experience.
The sprites are a great addition and they look fantastic. But I think everything else- the GUI (text boxes, font), backgrounds, should be altered to emulate the first RPGMaker version.
If you ever need any help with this I would actually be very interested. I see a lot of potential in this game and I would love to help you get it to the finish line.
