The RPG maker is the one source so far which has this "distinct" look of being non-isometric/diagonal. Which makes everything look like the same and which I guess is why this one reminds of a cheap RPG-Maker game on the first look.
I don't think a price was mentioned yet. But on KS it was 20$ and usually his games go for that price on steam. So my guess is either 20$ or 25$ max.
