Hungry Horace is a Pac-Man derivative game, which originally came out in the UK for the ZX Spectrum (in 1982), and then the Commodore 64 and Dragon 32 in 1983. In it, you have pick flowers (instead of food pellets, and you have guards (not ghosts) chasing you. You can get a bell (the power up pellet), that allows you to scare the guards and make them vulnerable. Unlike the original Pac-Man, though, there are four mazes to wander through, and they are all interconnected (you can travel to one without fully completing the previous one). There are some exits that are actually warp tunnels (like the side tunnel in Pac-Man, and others take you to the other mazes.
