App has a mass of bugs and glitches, removes colours, removes changes and after a while it has to be restarted since it won't even do half the things you need it to do anymore (as an example, i tried to make a black ring, and it just kept changing the black to white after some adjustments. Then, after creating like 2 or 3 more rings, it changed the black to white without an option to reverse it. So i had to restart)
