Snapper
_Snapper_ has a quite convoluted history. It started out as a faithful _Pac-
Man_ clone, and was even called “Pacman” straight until it was released, when
the name was changed to Snapper to avoid infringing on Namco’s copyright.
Nevertheless, this simple name change wasn’t enough, and subsequent releases
saw the sprites changed from the well-known yellow circle and chasing ghosts
to a yellow ball with legs and a hat, chased by humanoids.
One gameplay change compared to the original _Pac-Man_ is the behaviour of the
ghosts (or humanoids). Wherewas they all have distinct movement patterns in
the original, here they behave the same, each patrolling one corner of the
maze, but are let out of their pen in the centre of the screen at different
times, with the red one being let out first. As in the original, there are
bonus fruits appearing on each level, with the final one being – fittingly –
an acorn.
