I don't really know why I'm doing this.
If you can't figure out what I'm doing from that, its a WIP texture pack using various sprites from NES games.
For those curious:
Kid Icarus - dirt, iron door (the one on the right)
Super Mario Bros. - granite, daisies, mushrooms, andesite
Zelda II: The Adventure of Link - grass (and tall grass), oak logs + leaves (those closest trees), sand (not pictured)
Faxanadu - oak door (the one on the left), potions (not pictured)
Castlevania II: Simon's Quest - stone (+ ores)
And a bunch others not yet significant enough to be pictured.
Faxanadu especially will get more. It's too good not to.
EDIT: Caves are a lot more colourful now =3
Not happy with iron ore (the purple-blue blocks at the back), but Simon's Quest doesn't have any blocks with a colour quite fitting enough.
EDIT: Liquids! I was tinkering with water, trying to get it to look any good and accidentally made it look cool.
That's the water from the overworld of Zelda II and the lava from the Heat Man stage of Mega Man 2, with the palettes altered to match. Lava is much the same.
...actually, someone should make a mod that adds working question mark blocks that you can hit from below and get something out of.
I'm thinking a chest for obvious reasons, but chests have a convoluted texture.
I wish Battletoads had a more block-y sprite set. I probably won't be able to take anything from it.
In other news, Duck Maze just got a lot of attention, since it could do nearly all the coloured blocks by itself.
