The repeated locked upgrades that ask you to wishlist the game were already annoying enough, but I was willing to push past that since the game wasn't bad. Unfortunately, that stopped once it became about getting guilt, and almost every previous upgrade ceased mattering, and I became reliant on the random wanderings of these guys. Not a fun mechanic, and it becomes the entire game, very tedious, did not play past the first...5 or so guilt upgrades, I'd estimate.
