sorry for being late, i was having exams and was making some other projects while working on the new version, it could be easy to just update the sprites of the old version but i'm making a whole new app from scratch as an update and i will change it's name to pixel designer, you will be able to import and edit all your game assets includes , characters , robots, tilesets, and UI, also thinking about adding a music editor on the later updates and an internal image editor, i will publish the app for testing soon, i'm sorry again for being late.
