Spin-off of the doors: lost fragments

Not bad, much shorter than the previous one but just as enjoyable.
The only problem I have had is that a bug got me stuck in a puzzle that I needed to continue but restarting the game solved it.
It's entertaining but it seemed very short and had a very anticlimactic ending.
The story doesn't hook you much, but you continue because you want to know what happens.
I really liked the design of the boxes and their themes
