Status is that I lost interest in this game and fell down the Minecraft hole again for a month, but now I've had enough of that, so maybe I'll continue with this.
But now that the devs seem to be looking to change the art style of the game to something more along the lines of this (they used this thread as an example), this texture pack might eventually not be much of an improvement. I am very interested in seeing what kind of style the new art will have, if it changes at all.
And if it changes, dimensions of sprites, particles, and numbers of frames in animations might change as well, which means that many things in this pack would have to be updated and changed and who knows what would have to be done.
So if the art is going to change, maybe I will wait for it to happen. I am unsure.
