|Finished the game by getting the rest of the gems and gold relics in stages 22-30. The only other gold relics that were somewhat hard were the plane shooting level, and a platforming level where the water rises and I had to rush through without drowning.. There was another racing level where it's dark and you can only see the road/boxes a few meters ahead of you.. that was kinda hard but still fun. Thankfully there were no more swimming levels or extremely aggravating levels.|
Also one of the hidden bonus levels was another Coco jetski one, but it was an open ended area with boxes scattered around all over. I even had trouble finding the exit the first time.
And now I'm done the game, with 105%... obviously I'm not gonna bother with the platinum relics, that'd just be way too much trouble. You get the 45th gem and a fireworks display from Coco for getting all gold relics or higher.
