Pac-Man on Atari 8-bit home computers was first released by Atari Corporation in 1982. The same game was re-released by Datasoft in 1984, and by US Gold in the UK in 1985.
Players can change difficulty levels by pressing Option on the title screen. The game has eight difficulty levels and on the default setting (cherries) it is possibly the easiest version of Pac-Man I think I’ve ever played. Increasing the difficulty definitely speeds up the ghosts, but to say that it increases their intelligence is open to debate. I say that it doesn’t, and I found the ghost AI to be mostly pretty dumb.
The maze doesn’t change at all, but there are some cut scenes between levels.
Pac-Man on the Atari 8-bit isn’t great, but it’s a good choice if you want an easy game of it.
