Draw Me a River

Draw a creature. An AI teaches it to move. Physics decides whether it gets across the river.

Draw anything in the box: legs, wheels, a blob, a stick figure. The game reads your drawing like a skeleton. Closed shapes become hollow bodies and heads, circles under a body become wheels, lines reaching down become legs with knees. Then an AI learns a gait for it in a few seconds, right in your browser (you watch it learn), and your drawing sets off on its own.

The trick: most drawings won't make it. Hollow shapes pop on cone tips, the bridge has a hole, and something spiky hangs low. Every failure tells you something. Find the creature that reaches the flag.

• Lines are solid sticks; closed shapes are hollow and pop
• Every run is real physics: teach it again for a different gait
• Par is one minute
