I may be able to make something for you, as I am making my own game too. I'll try and make it somewhat like the examples you provided. EDIT: What engine are you using? Just interested
Bump Just added real time dynamic lighting to the pixel art. Which makes them into normal maps. It's really cool and I'll try and make an update video of it soon. It looks way more like a dungeon now!
Added lots of cool light sources and other things to do with lighting. Looks really really cool. Also found some really great music for the game thats free for commercial use. If anyone wants to see how epic it looks just ask and ill make an update vid
