What a charming little app. Thank you for making it. It reminds me of Flipnote, a game I loved to play.
However, I noticed that when the user draws at the edges of the canvas, their finger can accidentally slide over to the New button, erasing the canvas. Can you implement a measure that prevents accidental clearing of the canvas? Maybe a press-and-hold delay or a confirmation dialog can help.
Thank you, I plan on using this for some hobby video projects, because I love the minimalistic, but fun nature of it.
