Got it. However I think it is to harsh for a balance.
Well, I think it's actually well balanced, because after sleeping with someone in the city, the MC gets strength recovery, although not a full recovery because that "sleeping" costs additional energy. With the strength recovery, the MC can continue with her daily tasks. This gives you more flexibility, no need to return home every day, at the cost of being more corrupted.
To be clear, this game is not a game of brainless walkthrough or HCG collecting. It has some level of difficulty and needs some explorations and experiments to find the most efficient way to progress / corrupt. No item or skill in this game is useless. Spend all your money wisely, use the items and skills wisely. All the key information you need for understanding this game is in the "Realm of Consciousness", take some time to read.
