The game's core design as a 'surreal horror experience' with a 'stressful game loop' may induce significant fear and anxiety. The continuous nature of the threat and the lack of natural stopping points could make it difficult for players to disengage, potentially leading to prolonged stress. While not monetized, the game's design leverages loss aversion and near-miss mechanics to maintain engagement, which could be intense for some players.
