Its a really fun game. I have some ideas to make the game more user friendly.
- Add more control options like Arrow Keys
- I think the helicopter can carry just one cookie at once so I would set the pickup and drop to the same key like space or e (or both)
- I would add a change action too (on the same key as pickup and drop) so if you picked up the wrong cookie and you are standing in front of another, you dont have to press the button twice (drop your cookie and pickup the new) and the new cookie is instantly picked up and the old automaticly dropped
