00:00Did you know one person built Happy Wheels alone back in 2010?
00:05Jim Bonacci coded the whole thing himself, and it's returning on Steam.
00:09Most people think it blew up because of the gore.
00:12The real reason is physics.
00:15Bonacci used Fox 2D, a physics engine that gives every object real weight and momentum.
00:21So your character's arm snapping off isn't a pre-made animation.
00:25The game calculates speed, angle, and force live.
00:30That's why no two crashes ever look the same.
00:33Then came the level editor.
00:35Players built and shared their own levels, so the game never ran out.
00:39What would your impossible level look like?
