Hello, i saw the same red headed character in a new rpgmaker game on steam(survivor dieland), i first thought it was an original character because of the artwork (wrong way of thinking, i know)
Yeah, the graphics/audio are from the 3DS RPG Maker, same as the first Knight Bewitched. Hopefully I can crowdfund my next project and use original assets instead!
Edit: I should add that the art illustrations (ie the cover art and the hot springs scene in the screenshots) are original illustrations that I commissioned from an artist. The characters used in the illustrations are, of course, based off of characters from the 3DS RPG Maker.
