The current button is faulty, so push it out of the screen to the left and once you get a new one jump on it.
Jump just before the button appears in order to land on top.
Jump on the button until the laser fades out.

Jump on the slightly darker block on the floor to fall down. When the spikes retract, push the block along and headbutt the button on the ceiling.

Click on the button using your mouse.
Push the button to the left wall, then jump onto the platform above it, to make it fall onto the button.
Jump from higher ground to make the room shake and to make the button drop to the ground (This will take 3 goes).
Walking left shows you where the button is, but you can’t press it. You have to walk right and fall down, then quickly jump left and up over the platforms before they disappear.
After pressing the button, you will need to head butt the laser guns on each side to help break them.
Jump onto the button from the low platform. This will make you bounce higher to make it to the higher platform. Jump onto the button from the high platform and reach for the key.
Jump on the button, then walk half way between it and the left wall. Jump up to reveal a hidden platform. Jump up again, then far right and up again, revealing 3 more platforms as you go.
Jump up to the right and push the disjointed block. When you’re in the next room, jump on every second block as they will disappear and you need to leave yourself a way to get back.
The hint is in the level name. Press the button and don’t worry that the laser doesn’t disappear, as it’s only an illusion.
Jump on the button, then use the mouse to drag the key to the Yellow Ninja.
Jump on the button to make the laser flash. Make your way to one of the highest platforms and with the right timing, jump through the gap, pausing the game (with P) as soon as you touch the key. The laser won’t pause and you will need to un-pause (with P), at the right time to drop through the gap again.
Jump on the button and make your way the the top-right platform. Above the right laser gun is a secret passage you need to walk through. Once you’re in the next room, jump on the pillars making sure you leave yourself a way to come back (they move down each time you touch them).
