This isn't coming from me personally, but my friend who's playing the game on xbox 360 has run into this gamebreaking problem in the Red Mine.

There's a part of the level where you grab onto a sort of ledge and a minecart sort of falls on top of you which leads to you sliding down into more of the level.
However, his game seems to glitch out and soon after, he dies.
He's tried restarting the game and his xbox to no luck.

Not sure if related or unrelated, but the climbing hooks on his character seem to jitter up and down really quickly which also doesn't seem to go away.

Thanks for your time, hope you can help as he is really enjoying the game up to this point.
