I don't get the stetoscope part.. 

but appreciate playing hearts with that music vibe

Fun to play a card game I hadn't played in years! Well done with the chill implementation, very relaxing.

Hearts, nice. It was cool playing a card game in a game! I was not sure how to use the stethoscope. I could not hear a beat or anything, just the music.

It was difficult at first to discern which cards were which type due to the icon's size, but after a while I managed to remember. For some reason, the game did not continue when I had 4 cards left.
