Size Shifter Runner

One Slider, Two Solutions

Size Shifter Runner turns a single control into a constant decision. The character runs forward on its own, and a slider at the bottom of the screen sets its size. Slide left to shrink; slide right to grow. The obstacle in front decides which direction is correct.

Reading Obstacles Before They Hit

Grid barriers have open cells that only a smaller character can pass through. Stacks of boxes sit in the path and require a larger form to break apart. Because the character never stops, players must recognize the obstacle type early and adjust the slider before contact. The two obstacle families alternate unpredictably, so the correct size is rarely the one already set.

Stages That Keep Raising the Bar

Each stage adds new obstacle types and increases the pace, so the window for a correct size change gets shorter. That progression is the main source of replay value: earlier stages can be replayed to build timing habits before the harder layouts arrive. The game launched in January 2023 and runs on HTML5, which means it loads in modern browsers on desktop, phones, and tablets without installation.

Presentation and Session Length

Colorful graphics and a simple interface keep the focus on the slider. Full-screen mode is available and helps players see upcoming obstacles clearly. Runs are short by design, which makes the game easy to pick up for a few minutes, and the family-safe presentation keeps it suitable for players of all ages.
