Yeah, the Spectrum is insanely intense in general, and that original MM on it is just nuts.
Actually the dev’s follow-up, Jet Set Willy,
is way too nuts for me to handle
…also I guess kicked off the whole walk-around-and-collect-stuff craze on Spectrum (oh I think I got that idea from @MintyJuffowup platformers that arent metroidvanias or meat boy clones - #19 by MintyJuffowup but you can definitely see it
when looking at other Spectrum games ( amiga mini - #18 by meauxdal by @meauxal ) which I’m not really into. And they had to remove the music in the original versions, which was a rip-off of “If I Were a Rich Man.” ; D
And check out that copy protection:
