Simply Jetpacks Flight and Hover

• Normal flight - with the engine on, holding jump accelerates you upward; releasing jump lets you fall normally. Horizontal movement works as usual while airborne.
• Hover mode - toggled on/off (default key H). While hovering you keep a steady altitude, and instead of free-falling you sink in a slow, controlled descent - soft landings without fall damage from ordinary heights.
• Emergency hover - a safety net that engages hover automatically to catch a deadly fall. Its toggle has no default key; bind one in the controls menu if you want to switch it on the fly.
• Engine toggle (default key J) - switches the jetpack's engine on or off entirely; with the engine off, jump behaves as vanilla and no energy is drained.

Every toggle announces its new state on screen, so you always know whether the engine, hover mode or charger is active.
