Interesting idea to dig up treasures and fight against zombies. I do like the line of sight mechanic. What this game needs is some more ui elements like how much space you have in your backpack before you reach max capacity, also have the health bar show up in the shop so I'll know if I don't need anymore healing and most likely overspend on healing potions. Have all of the stats of the player be in the shop screen (health, item capacity, etc). And when you attack the zombies show visual feedback and damage indicator to show that I am hitting the zombies same way on how the zombies are hitting the player. Also I don't know if it's true but if you dig up all of the graves and you don't have enough gold for the antidote then is it game over? and is the bg music not looping for you? One more suggestion is to buy some weapons or an item in the shop to fight/ kill against the undead a lot better. Thank you.

Great work! I left some feedback on the game page :)
