OvO

A precision platformer about momentum. The stickman has a small set of movements — jump, dive, slide, wall jump — and each one preserves or converts speed in a specific way, so the levels are designed as sequences where stopping is failure and the only route through is one continuous motion. That design makes it a game about vocabulary rather than reflexes. Each level introduces one use of one movement, and by the later stages you are expected to chain four of them without thinking, which is only possible because the earlier levels drilled each piece in isolation. The difficulty is high and the fairness is absolute: the controls are frame-consistent, the hazards are static, and every failure traces to a specific input. Deaths are frequent and cost nothing — the restart is instant and puts you back at the level start, which is always seconds away. That loop is what makes hundreds of attempts at a single stage feel like practice rather than punishment. It is one of the better precision platformers available in a browser, it needs a keyboard to play properly, and it runs on anything.
