It's been a long while since I've been active here, but I was bored and decided to make a new avatar!
I thought of The Binding of Isaac too. It'd be cool if the black halo were also animated.
So awesome that you noticed that! I've been playing a lot of Binding of Isaac lately, so that's where the inspiration came from.
This reminds me several items and enemies from Binding of Isaac. I like it.
I really like your dithering
