Thank you very much for answering (I hope that one day it can be exported in 8bits); I have an other question, is it possible to cut something so that it can be moved around the canvas using a grid movement?
You can use a selection tool to create a selection, and then you can click on it to move it. If you hold `Control`, the movement will be snapped to the grid. You can read this for more information: https://www.oramainteractive.com/Pixelorama-Docs/user_manual/transforming#move
