You could look at ULTRAKILL, or a number of 3D Realms games for examples of work made with Pixel8r. It looks pretty good lit or unlit and you can always paint or bake more or less lighting into the textures depending on your needs. You can also preview in Painter with or without lighting. It does support normal maps, though I'm not sure of any games offhand which use them. I've made a few tutorials for Pixel8r showing off unlit, lit, and PBR lit workflows.
