I played a couple runs and a few notes: the do x things in order to unlock my true power relics don't work as every new round it seems the game forgets about the past data it acquired such as how many enemies you have killed. Similarly the -2 cost to all items in the shop seems to be bugged as the price of items resets when i try to buy the unit behind the item. Also the gain a second copy of this level or lower relics seem useless to me as usually the primary reason you would delay taking a relic is because of the possibility of possibly getting a copy of a higher level relic, but by taking away that possibility means you are just delaying the power you would get from just selecting the relic now for basically no upside. Also not sure how they did it but there appears to be some kind of bug in your game that allows you to get infinite money because 1 of my runs i ran into someone with a full board of 3 star vampires when my current shop only showed about a 20% chance of rare units appearing at the time.
