glad you enjoyed! And glad you liked the dithering effect!
typically i would use markdibarry's shader to add bayer dithering effects, which i credit in almost all my games: https://godotshaders.com/shader/arbitrary-color-reduction-ordered-dithering/
and then i found this vid by acerola where he talks about the IGN dithering pattern:
which seems to be super helpful in 3D enviornments for efficiency with shadows/transparency...
but it's also really cool in 2D too when you plug this in for the dithering pattern instead of the typical bayer pattern!
If you turn off the shaders, there's a lot of transparency and gradients so the IGN dithering has lots of in-between values to blend, like with the fading cloud particles around the Cloudotaur
