Seen: All Hidden Spots

So basically, all these achievements belong to the Main Game between the Beginning and Checkpoint 1…

Hidden Spot (1):

When starting the game and after getting the movement and jump instructions, you will find this small booth. When you keep pressing Up, you will be able to enter it. And that’s where you will get the 1st Hidden Spot achievement…

Hidden Spot (2):

After passing the annoying man, you will come across these two platforms with the pillars. I’m not sure if you are required to go behind one of the pillars only or both of them to get the achievement; but to be on the safe side, go behind them both. And that’s the 2nd Hidden Spot achievement…

Hidden Spot (3):

Directly after the 2nd Hidden Spot, you will come by these bridge-like things. Once you jump onto each of them, you will see that entrance to the top right. Once you go in, that’s where the 3rd Hidden Spot is…

Hidden Spot (4):

Also after the 3rd Hidden Spot, you will find these multi openings. There are 3 levels. Once you go to the extreme top (which is the 3rd level) and run inside of it for a bit, you will get the 4th Hidden Spot achievement…

Hidden Spot (5):

This one is a bit tricky. Right before you reach Checkpoint 1, you will see this pillar with the tiny platform. To get there, just hold the Jump button and then press Down twice to reach that platform. Passing through it is where the 5th Hidden Spot is…
