2D Sandbox game

Hi,

Been working on this game for around two weeks on and off when I have time, doing the procedural landscape generation which is using
a mix of perlin noise and cellular automata.

My blog website with latest screen shot is at:

Next is to add trees on the grass level, easy enough working out where to place them, but guess should use sprites for them and not add to tile array…

Any advice on how I could add some tile lighting? Maybe use shaders?

I’m using Libgdx and OGL.

Thanks,
Steve
