Thanks for playing and for the video! It was especially useful to hear your thought process throughout so thanks for including that.
It's good to know it can be completed without using sprint. Really the sprint is intended to be used to escape the monster if it sees you (you can sprint slightly quicker than the monster can run) so it's not essential if you can successfully avoid the monster. I don't know whether sprinting makes the game easier per-se but you can probably play less carefully if using it and, of course, if you use it outside of encounters it generally speeds up the game as you're able to explore quicker.
I'll have a think about the to-do list but my initial instinct is that will make it too frictionless and might decrease the tension. It was the intention that you don't know much until you explore and part of me quite likes that it's possible to think you can escape but you can't. On the other hand I can see how it could be frustrating. I guess if players always went to the elevator first it's alleviated because it tells you it needs power and a keycard. However I'm unsure how to encourage that to happen.
