What is amazing takes the fun away at the same time: The detection is way too fast/early. For example you are tasked to draw an octagon, the detection will already trigger once you drew three lines that are roughly aligned at 135° to each other. Draw an elephant? I can see there is something that remotely looks like a trunk and there is an attempt to draw an ear that's merely a stroke at this point. It's an elephant alright!
Things like that made me play the game in a different way: Draw it so the AI won't detect it but a human would most likely instantly recognize it. Example: Microphone. Just draw a microphone hanging from a two-segment microphone arm. Start with the arm and add the microphone last and draw a circle around it or point at it. Clearly someone would recognize this as a microphone, while the AI struggles and thinks it's something completely unrelated.
