Rebuilding Projectile Game

I rebuilt Projectile Game on Physics Zone. The old version had three levels. There are four levels now, ordered by which equation they need. Level 1 is flat ground. Level 2 adds a wall, and the derivation has a payoff: the speed cancels, so clearing it depends on the angle alone. Level 3 raises the cannon. Level 4 puts the target in the air, so the shot has to pass through a point rather than land at a distance.

The tutorial drives the live simulation rather than a mock-up. A hand glides to each control and operates the real thing – the cannon rotates, the readouts update. Which means the tour is mutating real game state, so everything it touches is captured on open and restored on close, however far through it the player quits.
