Hey thanks for playing the game! I'm one of the narrative designers. The text speed is something we're looking to tweak, so thanks for your input! As for the key issue, the first level has two pieces of evidence. The key is one of them, and you'll need to find the other before you can get through the exit door. Let us know if you need anything else, and again, thanks for playing!
