The concept is definitely interesting from a story perspective, a typewriter that writes back to you. Some qualms I have are that you aren't able to type using your keyboard (even though it was shown to be possible at the start of the game) and that I can't lower or see through the current puzzle to try and remember what the letters are that I could remember. The first puzzle I managed to get going because "It's" was the 1st word I could think of that has an apostrophe after 2 letters and ending with one. After that I got into puzzle #2 and forgot what letters corresponded to anything, and I had to scroll down to the comments/video just to remember. Audio is good, and you chose the best font for this kind of thing. Good work!
