Madness Blast

You control a lone soldier in a single, confined room. The goal is simple: survive. Enemies pour in from all sides, and you have to move left and right, jump over attacks, and shoot everything that moves. You aim with your mouse and fire with a click, which gives it a direct, responsive feel. The pacing is relentless; the difficulty comes from the sheer number of foes and the limited space you have to maneuver. It feels tense and immediate, a pure test of your reflexes in a crowded box.
