The Pico-8 is the most popular fantasy game console by a wide margin. We’ve already linked to Josh “cortex” Millard’s Ennuigi, which is notable enough to have its own Wikipedia entry.
Ennuigi was more of an extended joke than a game, though, while Pico-8 Moon Patrol is no joke; it’s substantially harder than the original arcade game, putting you up against harder obstacles earlier. Sometimes it doesn’t feel fair when a flying saucer drops a bomb at such an angle that neither speeding up nor slowing down could have avoided it in time, although it’s possible, in this version, to shoot down the bomb before it strikes you.
Give it a try! This video is my best run to date, getting through the first three sectors:
