🟦 Geometry Jump

One button, one brave little square, and a whole lot of triangles. How far can you get?

How to play: The square runs on its own — your only job is jumping. Tap the board, click, or press Space / ↑ / W to jump (hold to hop again the instant you land). Triangles are instant doom, blocks and slabs are safe to land on, and some slabs have spikes underneath — stay up high. Reach 100% and the course loops, faster. Death is cheap: retries are instant, and your attempt count is a badge of honour.
