Jumping Jack - Halloween

"Jumping Jack - Halloween" is based on the classic Spectrum platform game but with a spooky Halloween flavour.
Guide Jack to the top of each stage by jumping through the moving gaps in the floor.
Jumping into the floor will render Jack unconscious for a short time.
Avoid falling through the gaps below.
Gaps moving to the right travel downwards.
Gaps moving to the left travel upwards.
Reach the top floor within the time limit to complete each stage.
New hazards will be added on each successive level.
