About This Game

  • Concept. A psychological puzzle game where numbers become a physical limitation. Fingers represent available digits, and losing them permanently restricts player input.
  • Goal. Solve as many math problems as possible before losing too many fingers.
  • Gameplay. Each round presents a math problem. Correct answers advance the game, while mistakes, hesitation, or cheating result in finger loss. Blocked digits can no longer be used, forcing alternative calculations using remaining numbers and operators.
  • Controls. Keyboard input (numbers and operators).
  • Feedback. Visual distortion, screen darkening, red lighting flashes, heartbeat audio, sound effects for correct and incorrect actions, finger-cut animations, and game over screen.
  • Tech. Unity, URP, 2D Lights, post-processing effects, audio-driven feedback, procedural math generation, WebGL build.
