game is ok, got stuck in the mid clearing puzzle and had to restart the entire game. Also got stuck when trying to find the key to the cell (left the shed early and couldn't go back in) and gave up
Sorry but can you be a bit more clear about when? I've looked through that part of the game where you enter the storage shed, but I couldn't find any issue myself.
If you meant leaving after finding the "fake" keys and not being able to get back in, that's intentional. You're supposed to go back and follow what the character said inside the shed.
But if you managed to leave before even finding the "fake" keys, please tell me so I can look into it further.
