About Test Subject Blue
Test Subject Blue drops you into a sterile lab with a simple mission. You guide a small blue subject through compact chambers with a single view. Grab the key and reach the door before hazards shut you down. A compact blaster helps with threats and tricks. Teleport nodes fling you around and change how both you and your shots travel.
Each stage adds a clear rule and sticks to it. Bullets can pass through portals and hit switches that sit out of reach. Green organisms patrol tight platforms and block your path until you time a clean shot. Conveyors, one-way gates, and acid pools force you to plan routes. Some rooms ask for quick jumps. Others ask for measured pacing and careful aim.
The game feels tight and fair from start to finish. Controls respond fast and restarts kick in without delay. Pixel art keeps shapes crisp and the lab theme stays readable under pressure. Music sets a steady pulse that suits the tests. The curve climbs in small steps and teaches as it goes. By the last chambers you think ahead and act with purpose in each small arena.
