I've never tried it, some of the finer details will be lost but I dont see why it wouldnt work. If you do it, let me know if it looks ok.

I ended up buying the pack expecting to do a bunch of cleanup work... But these aren't 128x128 at all? they are much closer to the 64x64 size already lol.
Sure the textures themselves are 128x128, but most of that is just empty unused space in the texture. I don't really understand why you use 128x128 when that is clearly not the actual scale of the zombies.
This is good news for me however :) these will most likely be used in the steam game "Sombie" ;)
