The corridor and toilets reminded me of the Amazing Escape the School game. The music sounded familiar, too. There were only two locks to solve and four coins to find. To me, it's a short and easy episode. A bag of soil was found and left unused.
In the next episode, I might need to crack the password of the computer or find a wrench to turn on the water taps.
And yea, the fourth badge didn't work for me.
