All who pre-ordered the game can play the demo version of Crash Bandicoot 4. This page of the guide has a walkthrough for the Dino Dash map.
Number of chests
There are 159 chests on the Dino Dash map.
You encounter enemies right after the level starts. They move in a straight line – from left to right – this makes them easy to avoid.
You will also come across enemies spitting acid. Avoid their attacks to keep your health points intact.
The next task is to slide down a liana. Avoid the obstacles on the way by jumping.
In the next part of the map, you will encounter a hostile dinosaur. Avoid the swamps, destroy the bones and run as fast as you can – otherwise, the dinosaur will catch you.
You will come across spikes. Slide under them to avoid the trap.
Other sequences where you run away from the dinosaur look the same as the first one. Avoid every obstacle so you won't get caught.
The level ends when you manage to escape the dinosaur and magma.
The entrance to the secret level is near the dinosaur, on the curve. You can easily miss it if you don't know how it looks like. Check out the picture above and memorize that location.
The secret level is full of Wumpa fruits and TNT. Be very careful when collecting the fruits.
