Make a function for the sitting orc in the first stage, so that he sometimes goes to check Nesche, if Nesche is in the room, with some probability she will be raped or put on a collar and taken to the room with the end of the game, where Nesche is raped by 2 orcs in shackles, after which Nesche will be put on shackles again, and if not, the orc will scream that the slave has escaped and will run to look for her in all the rooms, and if he does not find her, he will go to walk from the first part of the first stage to the second, sometimes going into Nesche's room, if he finds her there, he will go to sit again in the room where he was, the same will do the second orc, who is in the second part of the 1st stage (he will run around all the rooms looking for Nesche, and if he does not find her, he will go to walk again), the higher the difficulty, the higher the frequency of checking Nesche.
Although you could make a level that teaches players the mechanics of the game, for example, a level where the village where Nesche lived was attacked by orcs and she had to hide, while trying to escape, but eventually she would be noticed, captured and made a slave, at the same time show how Nesche became a slave and let new players get acquainted with the game mechanics before the start of the game itself, and the title of the level itself would be an introduction or something similar, also make a function in the gameplay settings that turns off the training, because I'm tired of seeing this training every time.
