yo, thank you for playing! iirc the graphics in this one were made with unlit materials using shared image texture atlases -- something like this:
No problemo, it's a fun and hilarious game.
I prefer Imphenzia's method of using a single pixel for each colo(u)r in the texture atlas. The video also doesn't mention anything about how to get the "unlit" look, which is what I was after. Sorry for not specifying ¯\_(ツ)_/¯ still a relative n00b at gamedev/3D. But I think I might look for "diffuse" materials and see what those do.
