Wow !!! This is the best horror visual novel I ever found on a smartphone ! (I purchased it on Android) Thank you so much for this game haha ♡
(A dev question : Is this game really made with Ren'Py ? I see no lag O.o everything is so smooth !)
Hello Amethysts! Thank you so much for playing The Letter! We're very glad you loved the game! :)
As for your question, the game is made in Unity.
