Experiment 00 description

Experiment 00

Experiment 00 is a vertical platformer built around the tension of climbing upward and slipping back down. You play as Subject 00, a squishy little slime who wakes inside a very serious research facility that is absolutely not on your side. The environment leans into a clinical mood, with clean lines and cold lights, while your tiny creature’s curiosity and stubbornness push you to climb higher regardless of the odds. As you navigate the maze of labs, test chambers, and corridors, the facility’s atmosphere presses in—yet your own momentum keeps you bouncing toward the next rung.

The core loop is simple but merciless: jump up through the vertical maze, savor the lift, then brace for the inevitable fall. Every jump counts, and every descent is… educational. Missteps aren’t failures so much as feedback, a data point that you’ll use to shape the next ascent. The game treats gravity as a tutor, teaching timing, momentum, and restraint. Each fall becomes a lesson, a chance to rethink your approach, and a reminder that progress often comes after a stumble.

The tone blends encouragement with playful cruelty. The game might cheer you on when you latch another platform. It might tease you for a missed jump. It might quietly remember if you gave up, nudging you to try again. But don’t worry—falling is normal here. In this facility, everyone slips from time to time, and the only real rule is to rise again. The challenge isn’t merely to reach the top but to persist with wit and grit as the walls rearrange and the path reveals new chances.

Your mission is to push beyond the present height, not by bravado alone but by consistent, careful decisions. Obstacles test your reflexes and your patience, forcing you to improvise with a body that can stretch, rebound, and squeeze through tight gaps. The vertical space rewards steady practice over flashy tricks. Each segment offers a new layout, inviting you to memorize patterns, exploit small margins, and refine your timing to gain every extra inch of altitude.
