There are some very challenging sections, some are embarrassingly obvious after you figure them out, others are a lot more vague.
General tips:
- If there's a beam of light firing into the sky, you probably need to go there to collect or activate something to move forward
- Aqua / blue coloured statues and things need to be yelled at to activate, sometimes you need to move yourself or things around to be able to activate them all to trigger something, open a gate, etc.
- All of the ledges you can grab or climb have a beige/white edge to them, if you are stuck look around for them as they may be your path forward
- If there is some thistle you need to break through, find a fruit tree nearby and lead a boar to the thistle, it will crash through when you throw the fruit through it
- If there's a pedestal you can stand in and look through you need to shift the camera around to "build" something, open a door, etc., sometimes you need to move objects around or rotate the pedestal to complete the task
- The fox companion you get early on usually leads you to the next task you need to complete, follow it and try to find out what to do to advance
- If you are trying to find all of the collectibles, chasing your fox companion will have you running past a lot of the searchable areas you need to explore
- If you care for achievements/trophies there are MANY that can be missed, often by accident, consult a guide if you want to do it in one shot or know that you can revisit the levels AFTER you finish the game
If you are absolutely stuck, this is a very good text walkthrough with some images.

I prefer text, if you want a video one there are many you can find on YouTube.
