Wow, very nice update ! Good work :D

What should I implement next?
A readme ? :P
Maybe even an ingame readme in case people forgot which was the key to do some specific action.

Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

Indeed. When I tried the program I had to search through a dozen of pages of replies just to find the controls and I still felt I missed some.

I didn't follow development but the fact that you pulled off a textured voxel engine (even though without lighting) at a pretty decent speed is quite impressive.
I find lighting rather annoying. And what's the difference between a "voxel engine" and 3D triangles? AFAIK a voxel engine is optimized for different sizes of voxels and has a better storage and rendering algorithm (most of the time with octrees).

That looks really awesome! This is the first time I tried it on a real calc, and the speed is really decent. 
I think it's a little weird that it says "loading" when exiting, though.
I didn't want to make a second "Saving" image.. But I'll fix that when fonts are working!

Umm, README.md has been there since v0.7.2.
A ingame readme would be nice, but I'd have to add font rendering first.

Well I thought voxel engine = cube tilemap renderer but w/e. :P

New feature release: v0.8!
New features:
- Crafti now uses block data (8 bits per block), which means your save files won't be compatible
- Torches in all directions (even upside-down)!
- Flowers!
- Mushrooms!
- Spider webs!
- Cake!
- Faster chunk culling!
- Ability to load external textures ("/documents/ndless/crafti.ppm.tns") in PPM format (24bit binary)
- A splash screen (From the internet, I only added the text "crafti")!
- Message "Loading" now shown when crafti is doing some heavy processing
- Disabled the mode with textures disabled, it was too ugly and slowed down the startup somewhat

Bugs fixed:
- Clock on screen

Known issues:
- With HD textures the block selection menu becomes unusable (but 1 and 3 still work)
- Front side of blocks is fixed (all furnaces face the XY-Plane)
- CLIP_PLANE too close
- Can rotate more than 90° horizontally, which turns the screen upside-down
(I'll probably fix all of them in v0.8.1, but that'll likely take a while)

Screenshots (BTW, hd textures don't make the game slower  ;) ):
     
     

What should I implement next?

And BTW, I'd be very glad if anyone could design a better menu or "Loading" message for me, I suck at art  ;D

My goodness, that looks fantastic! :D

For fonts, you can use nGC or Freetype (which works without any changes)

Does nGC support rendering into (raw) buffers with different width than the screen?

How big is Freetype? Doesn't it need a .ttf for rendering?

Writing a custom font rendering routine is easy, I only need two different font sizes, and I need real performance.
nGC uses the OS' font routines AFAIK which are slow and ugly, Freetype is probably slow as it's using splines, bezier-curves and such things.

I need speed because if I want to show text above a changing background, I'd have to render it every frame and transparency doesn't work with black fonts. I could probably find a workaround but rendering text into a buffer isn't exactly brilliant.

I don't remember the details about freetype, but I can give you a sample program. It is fast, and not that big.

Do you need a fire extinguisher? You'd have to pay the shipping cost, though :P
JK, it only crashes for me if I use a HD texture pack and open the menu. It overflows the screen buffer.
If that's not the cause, could you tell me your ndless revision, and if you know how to trigger the crash, could you upload your savefile and tell me how to reproduce?

Hm, could you compile freetype into a static lib and make a pull request on github.com/OlivierA/Ndless? I'm sure it'll be useful. You should also include the sample.

Gotta say, this looks incredible! Liking the new texture update.

Wow, I'm not sure what else to say.

This looks amazing.

Well it depends whether you use a vector or bitmap font anyway. ;) Of course the latter is faster but the former scales better. Also with bitmap fonts you'll most likely have to scale down, which is much slower than scaling up. So maybe there isn't that much of a difference.

Sure, I can do that :)

EDIT: While Im working on that, I would like to report that I also got a random crash. I unfortunately did not keep the savefile.
