OK, so it’s not on an actual Spectrum. I’m playing Fish!, a text adventure co-written by ex-YS chap Phil South on Fuse, a Spectrum emulator. On my Mac. Yes, it is complicated.
So far, I’ve become a goldfish (or perhaps I’m a fish all along?), spent ages trying to figure out how not to be swimming upside-down (“turn upside-down” seemed to do the trick), and completed the first of three “warps”. How about some screenshots to show you, eh?
