Thank you so much for playing and the feedback!
The witness statements aren't all necessarily just entering in exactly what the crew said - there may be some logical explanations for what some of them experienced and you have to make some deductions there. You could try figuring them out even without solving the doctor's puzzle. I understand those kinds of puzzles may not be fun for everyone. In case you'd like to continue the game, you could look at the walkthrough file in the downloads section for a solution to the doctor's puzzle. Either way, I'm really glad you enjoyed the setting! :)
