A game-based evaluation system embeds randomized substage templates into a side‑scroller called Planet Saga, logs 225 players’ runs, and analyzes outcomes with Item Response Theory (IRT) to produce item characteristic curves and per‑player ability estimates. Comparisons show audio playouts clear substages faster than touch with a dot‑matrix display, while audio and a tactile controller produce no significant difference, and disability groups do not differ. A linear programming simulation finds 12 substages reach homoscedasticity ≥50% and 15 substages ≥90%.
