Getting started
Lately, I’ve been thinking about some kind of synthetic looking isometric 3D world, and I might go with that; not sure yet. Played around a bit in GIMP and came up with this:

I imagined a bit more neon glow, actually; a bit like the “overbright” glow on an old CRT, or something like that. Oh well, that will work for now! (And yes, the block is of course actually a monochrome texture, so I can modulate those to whatever color. That might be fun!)
Now, coffee, and then code and engine and figure out what to actually do in there! ๐
