Time Trial

Time Trial is a mode that was first introduced in Crash Bandicoot Warpe . You try to race against the clock to the end of the level. There are time boxes spread around the level. If you break one of these the clock will freeze for a a period of time. The time the clock stays frozen is indicated on the box. And you will get a diffirent relic based on your performance. There are sapphire, gold and platinum.

In CTR if you managed to break all time boxes your time would be decreased by 10 seconds.

It also seems like there would have been a time trial mode in twinsanity as well but it was removed for uknown reasons.
