I’ll point out that there is no karma points in the game, but in the way of visual novels, the karma system is actually there. Your choice of actions will have consequences. Some of the choices is not that one-sided as it may seem. Like if you’ll give a sick drunk bum a large amount of money for a valuable information, he will die of alcohol poisoning soon after and will give you nothing. So you need to look at the circumstances first.
You’ll get a hints maybe, but that’s the field where the game will not going to hold your hand and lead you through it, everything you do here is on you.
