Hush!

Hush and make your way out! Don't walk fast for too long. Squat down and move on your tiptoe, otherwise, you will be caught!

CONTROL : WASD to move, Space to jump,  Hold Shift to squad down, F to switch from pull/push.
NOTE: use full screen to have smooth control of the view.
The online version may be laggy, here is also a full playthrough.
