Cool game! It's fun, it has it's own mood, and levels are interesting. Controls are a bit tough, it's sometimes hard to execute what you I had in mind (for puzzles games, you usually want your player to perform the task easely once figured it out). Post process is great, maybe just a tad over the top.
Small tips: for typewritting in Unity (with TextMeshPro), don't write the text letter by letter. Instead, change the maxVisibleCharacter property over time. It would prevent words starting to be typed on a line then falling suddently onto the next one.
