I love this app, it's great for doing pixel art and animation, but there are a few things that need to be fixed.
For one, the RESET button (the button that clears your canvas) does not have a "Are you sure you want to clear you work?" option, and if you mis-click, you're work is automatically gone.
Another thing is sometimes when an Advertisement pops up, when the Ad is done, the app logs itself out, and your progress is completely erased.
I have an idea to fix this: give the canvases a SAVE option, so if the artist has to go somewhere, they can Save their work, then log out of the app with their work safely still available when they come back.
There should also be more than one Save option, because somebody may be working on more than one pixel art.
