Chariot Achievement

You can do this achievement using two controllers.

Start off the level (Woodland Vestibule 1-1) with 1 character's item as the magnet and the other character's as the repulsor.

There aren't to many difficult parts in this level and alot will be trial and error. It's easier to always position the character with the magnet equipped in the elevated positions, jump with this character and then press Y to attract the chariot towards you, now with the second character use the repulsor while the chariot is still in the air to repel it to the elevated platform (unless you are able to place the repulsor character directly underneath). Where possible stand directly underneath the chariot and use the repulsor to send it directly up in the air. Then use the magnet to pull it towards you.

After you have done so, you'll then unlock the achievement.
