Fullscreen Mario
Fullscreen Mario is the full plumber remake in HTML5: mushrooms, flags, warp pipes and precisely the physics your thumbs remember, playable in-browser at, indeed, full screen.
The remake's faithfulness is the feature — jump arcs, turtle-shell billiards and all.
Tip: hold run before you jump, not during — Mario's long-jump distance is set at take-off, a truth that has ended a million pit-crossings since 1985. The mario games tag warps onward.
