Commissar Betrayal

You control a lone soldier, moving left and right across the screen while firing at waves of enemies that approach from both sides. Your main goal is to survive each stage by eliminating all opposing forces before they can overwhelm you. You use the arrow keys to dodge incoming fire and the control key to shoot; the spacebar lets your character jump, which is useful for avoiding ground-based attacks or certain projectiles. The pace is relentless, with little downtime between enemy spawns, and the difficulty ramps up quickly as you progress. It feels like a constant, tense scramble to maintain your position and outlast the onslaught.
