Paku-Paku works just like regular Pac-Man, it even looks like it. Basically, it is Pac-Man, eat the dots going around a symmetrical maze while avoiding the ghosts. Eat power pellets to eat the ghosts. The whole point is to get a higher score than your friends.

The game will run on pretty much any IBM Compatible PC including the original as long as you have a CGA card or better. It runs in 160x100 pixel graphics mode (a mode rarely leveraged until more recent "retro games" started coming along in the 2010's), and has support for many early sound cards including the IBM PC Jr/Tandy 1000, Creative Music System/Gameblaster, and Adlib FM Synthesizer cards. This alone makes it better than the previous "champ" (pun intended) CHAMPgames "Pac-Em'" - which will also be on this site at some point.
