Lot of new things added, you should check it out :)
Working on a big update that will include:
- Shop: Can purchase new cards and cards upgrades between each enemy encounter
- Card Upgrades: cards can now be upgraded to have special features, such as granting extra gold, damage, shield, etc, and even a transparent card upgrade that allows you to see the card face up even when its face down :)
Will be released soon, just have to do some polish!
