Feed -- Click on the canvas to place food. The fly will seek and eat it when hungry.

Touch -- Click on the fly to touch it. Location matters: head, thorax, abdomen, or leg each triggers different grooming. Tap 3+ times in 4 seconds for a pain response.

Air -- Click and drag near the fly to blow wind. Drag distance controls wind strength.

Light -- Cycles through Bright, Dim, and Dark. The fly exhibits phototaxis toward light.

Temp -- Cycles through Neutral, Warm, and Cool. Warm makes the fly more active and avoidant. Cool makes it exploratory.
