Wow :) even the floppy drive sound is present 5+
And it is not that hard at all! Took me 32min to win second time.
For new players you have to run until you spot the enemy blue bar at the bottom. Then at one point you can rewind if you get killed I used this 3 times ;) on last run... great job = pure retro joy!
