Canabalt

Canabalt is a fast-paced HTML5 endless runner that defined the genre with its minimalist design and adrenaline-pumping action. Set in a crumbling cityscape, players take control of a lone hero sprinting across rooftops, leaping over gaps, and dodging falling debris all in a desperate bid to escape an unknown catastrophe.
The gameplay is simple yet highly addictive: a single tap or click makes your character jump, and timing is everything. As the speed gradually increases, quick reflexes and sharp focus are essential to survive. One mistimed jump can send you plunging into the chaos below, ending your run.
Canabalt features sleek black-and-white pixel art, a dynamic, atmospheric soundtrack, and smooth, responsive controls. The minimalist aesthetic keeps the focus on fast action and precision timing, while randomly generated levels ensure that no two runs are ever the same.
