Well, the sound effects and background music are awesome in setting the mood. The thud sound for a card being placed on the table was well chosen. I felt the rain sound effect had too strong an attack, so I interpreted it as a keyboard typing sound at first; when the gameplay started, it became slightly more obvious it was describing the rain. The music with sustained strings feels mysterious and matches the visuals nicely.
However, I couldn't quite understand how to play the game. Maybe a bit more in-game onboarding might help. Perhaps try introducing one mechanic at a time if that's possible?
Anyway, great job again with the atmosphere.
