Thanks to 夙无囿 for pointing out in their review that the game can freeze if you refresh the shop often enough. Previous playtesters had apparently not amassed enough wealth to trigger this condition or simply had found what they were looking for earlier. Either way, this bug has now been fixed, allowing you to refresh the shop as many times as you'd like!
And in order to keep all this refreshing worth your effort, I've added 3 new artifacts to the game. Two of which will allow you to gather even more gold, for even more shop refreshes! Best of luck <3.
