Bet you didn't expect to be reading about a game named after deprecated multimedia platform Macromedia Flash in 2020.
Mackerelmedia Fish is the latest creation of indie designer Nathalie Lawhead, in which you play an internet archaeologist exploring a crumbledown website as it falls to bits around you. There are minigames tucked away within it, and a big fish to find, as well as a rat who eat bits of old webcode and some inventive Error 404 dead ends. It's a bit like Frog Fractions and a bit like Hypnospace Outlaw, and Lawhead calls it "something between an ARG, graphic novel, and text adventure."
It is definitely a text adventure, because I was eaten by a grue.
I've had Mackerelmedia Fish open in another tab while I work so I can duck in at my leisure, discovering things like a downloadable "electric love potato" desktop buddy and trying not to fall into the dark. It's a cheerful window back into a time before social media when there were a lot more colorful, amateurish personal websites and everything felt much friendlier online.
You can play Mackerelmedia Fish here. Lawhead is also responsible for Everything is Going to Be OK, and contributed to the PC Gamer Indie zine.
