Added a discard pile that matches the theme of the game. Credit goes to Sir_Charles(https://psteamcommunity.yuanyoumao.com/profiles/76561198081176522)

Added snap points in marketplace for easier card placement

Changed the name of Diamond coins and cards to Ruby which is more apt seeing as the cards feature a giant Ruby.

Flipped the tablet so you don't see the screen. You can always unlock it using the key 'l' and flip it to pause/replay the background 'music'

Fine-tuned some of the cards and the discard pile.
