In this manner, Can you beat DDLC without deleting Monika?. If players don't delete Monika at this stage in the game, they will only be able to speak to Monika when they return. Not just in another room, but after she herself has deleted the rest of the game.
Likewise, What happens if I dont delete Monika? Players also have to be careful not to delete Monika too early in Act 3, because if they do so without seeing the CG, the game will not count it as seen and they will just see the Normal Ending. After Sayori, Yuri, and Natsuki's CGs have been seen, the game can be continued normally.
