Crash Bandicoot/Hog Wild

You have to ride a wild hog through a local populated village. You can't stop until the end, just move left or right. During the ride you have to avoid various obstacles and jump over gaps, breaking the boxes that are on the path. To overcome the longest gaps, you will first have to jump on some kind of drum, to gain extra high. At regular intervals there are C-boxes, from which you can restart the ride in case of death.

Obviously, you can't go backwards to smash boxes you missed, so, if you want to get a clear gem, you must hit all the crates on the first try, without losing lives.
