making a jumping game in xcode macbook pro

Begins a new Xcode runner game where tapping makes green-block “Hank” jump and fall toward a floor. Implements NSTimer movement every 0.05 seconds; tapping sets hankJump to 30, while falling subtracts hankJump from Hank’s vertical position. The prototype stops on the floor but permits repeated jumps and sinking, leaving jump limits and collision behaviour unresolved.

Continues iterative Xcode development, shifting from zombie shooting toward runner-style movement.
