I am sorry to hear you are having these types of comments levied against you. I cannot speak for everyone, but I love your writing and the world you have created with such vibrant characters. While you might not claim to be much of an artist, I adore your style and think you should be proud! This game has so much promise and I cannot wait to see where you go from here!
And as far as the backgrounds, the only comment I have is that they capture the world you have made wonderfully! My only critique is I miss this little guy, living his best life sunbathing! lol
