One Block Survival is a 2D puzzle platformer that blends classic block mechanics with character-driven puzzle solving. You control tiny creatures called Tetras that can transform into different block shapes. Use their transformation ability to create platforms, bridges, and stairs so the Tetras can reach the glowing exit portal on each level.
The core objective is simple: move the Tetras and change their form to fill gaps and connect routes to the portal. Each level presents a compact puzzle that tests spatial thinking and timing. The game rewards planning and careful placement of blocks rather than fast reflexes. As you progress you will face more complex layouts that require creative use of limited moves and clever stacking. One Block Survival appeals to players who like calm puzzle challenges and platform style problem solving in short play sessions.
