It took a fairly while to get used to the controls of the game---finagling with the inventory/holding item system and figuring out how exactly to write and seal letters was a bit tricky---but once I figured out I had a fun time getting into it and writing letters! I like the rhythm of having to get up from the desk to put away the letter, only to come back and see another email. That said, stuff like getting the pen or envelope ready could sometimes take the steam out of the gameplay.
The idea of this soulless world where writing is now a thing of the past and done by writers trapped in rooms was pretty neat, and I liked how that blended with these glimpses you got into these people's lives and loves! Not sure how the letters were graded in the end, but tasks like writing a poem in iambic pentameter were fun enough where I was willing to play along and really get into it---I think more concrete and fun tasks like that that really make you approach the letter-writing in a very intentional way would be super fun! I think I spent like five minutes just having fun riffing on an iambic pentameter poem, which was a fun time!
Good work, and thanks for sharing! :D
