Hi, sorry, I have been very busy.
If you want a 5×5 pixel grid that is possible but you have to edit your grid settings and upload new grid images as the ones there are 10×10 blocks.
This also could take up more memory to process, I am not sure. So if you get out of memory errors you may have to adjust that setting as well.
If you still need help with your issues still please let me know.
