Minima

The Land of Miskatonia needs a hero to save it from the evil Faxon and its minions. Can you be that hero? Explore Miskatonia and its settlements, talk to its residents, build up your skills, and finally challenge Faxon in its secret lair.

Minima is an adventure RPG in the style of the older Ultima games (Ultima I, Ultima II, Ultima III, Ultima IV, & Ultima V) as played on the Commodore 64 and 128 computers. Just like the original Ultima games, it includes a world view, enterable towns, and 3D dungeon displays. It also features graphics, sound effects, and music that should help one recollect those classics. More importantly, it is a fully playable (and winnable) game with its own backstory, plot, setting, and characters. It was written for PICO-8 and can be run on Linux, Mac, and MS-Windows. It can also be played through the Web here.
