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…
That's how I play this too! I've found it's very very bad at dealing with rotations. Carrot right side up? No problem, carrot at a 230° angle? It'll never figure it out.
