Rapid Rabbit Rush

Rapid Rabbit Rush is a browser-based HTML5 casual runner-platformer. A rabbit sprints through spike-filled environments collecting carrots and reaching an exit portal. Forward velocity builds progressively while the directional key is held — not instantly — so the double jump’s horizontal reach grows with sprint duration. Sprinting for two or three steps before jumping covers significantly more distance than jumping from a standing start.

Brake stop deceleration scales directly with current speed — a full-speed rabbit needs much more distance to stop than a half-speed one. Release the directional key three to four steps before any spike corridor entrance, not at the edge itself. There are no mid-level checkpoints: any spike contact resets the full stage from the beginning. A safe, slower run that reaches the portal is always worth more than a fast run that resets.
