It took me about an hour to do this, and it worth it (no). This game has some interesting mechanics:
- Boxes fall at the platform, they can't just fall out of the screen
- You can carry boxes on yourself
- Boxes can stuck midair if you stop midair with a box.
This allowed me to push the box on the left side of a screen. I tried to do it with a golden box, but after a lot of attempts I gave up. I think that 2 golden boxes at both sides may be enough to get a high score, since there are a lot of batteries falling out of the sky. For now, as a proof of concept, take this little brown box.
PS. I love the game :D
