i doodled smth in my notebook and i liked it so i wanted to try drawing a slightly dif. version on this app but like i think this painting is actually cursed now??

not bc it looks bad but like, multiple times, while working on the bg i wanted to use, i messed smth up and went to undo it, and both times i did so it completely f*cked up all of my button's (& the touch screen's) reactivity to anything except for the a, x, home, and power buttons?? wth?? why did this happen?
