English Version: The Lesser Evil is a 1-bit style survival game where players must evade monster pursuits and use flashlight energy to defeat enemies within a confined space. Its unique feature is the “negative buff card system,” which increases difficulty through forced curse card selections after each level. These cards range from visual interference (e.g., screen inversion/ink/raindrops) and operational restrictions (e.g., disabling directional keys/slippery floors) to core mechanic削弱 (e.g., halving flashlight energy/death penalties). However, the author points out that over half of the visual interference cards, while superficially increasing difficulty, disrupt players’ control over the core “hand-eye coordination” anchor, leading to frustration rather than a sense of challenge. In contrast, adjustments to resource management (flashlight energy drain) and survival pressure (collision volume) create more engaging challenges. This design imbalance highlights an essential principle in game rule design: true challenge should be built on strengthening core mechanics, not by artificially increasing difficulty through interference with the player’s perceptual system. As seen in the success of classic bullet-hell games like Ikaruga, the most brutal challenges require the clearest foundational rules to ensure fairness.
