Thank you very much!
Yes, that's correct. It's planned to be a 16-bit version of the "8-bit Retro Graphic" with an overall nostalgic feel. The "8-bit Retro Graphic Materials All-in-One Pack" took a whole year to complete. With the increased color depth in this 16-bit version, the production time has unavoidably extended, so it might take around two years to remake everything.
For now, the next project in line is a set of walking and face graphics that will be fully compatible with these monsters. I hope you can patiently wait for it!
