As he writes where is a lot of optimisation work ahead.

Impressive !
Does this use mode ? How to make sure everything works with only 256 colours ?

As he says he uses mode 4 (240x160x8).
AFAIR Tomb Raider 1 on PC used 320x200x8bpp and 256 colours are native for it.

I would love to port this to 3DS, I want to know if the 3D mode makes it easier to judge things. I would think it could probably run the game fairly easily.

It seems to me he plans to port OpenLara to 3DS too. And Wii and GameCube also. But it's unclear and I'll ask for sure.

There is other ports of OpenLara on github page including version for 3DS (also 2DS) with autostereoscopy support. It's not finished, no shadows and I didn't decide what to show on the second screen... but it's fully playable especially on the New 2DS/3DS

DS, GameCube, Wii and Wii U in my plan.

For now GBA version is just a tech demo. I use mode 4, mode 5 is optional by simple define in the code, but I didn't get a significant benefits with it. Shading works via palette indices remapping table by the light/fog intensity value 0..31. Probably I will add some physics and animation soon, but framerate in some cases drops to 6 FPS.

That is very impressive.
