Team Building Escape Game - Careless Contamination Theme

To me, the whole set is not well built; the backstory is rather inane the decoder wheel was stuck and did not spin. there are only three puzzles in the whole game. The last puzzle is relatively hard, involving several steps and I would think could frustrate students.. I try and get any escape-room puzzle game and have played about fifty of them and I felt this was the most disappointing one.
