Good memories. Head Over Heels (C64 here) was one I used to just stare at, waiting for the next animation, musical cue, or room reveal...it was very well put together.

(Oh, and the title always made me wonder if it was a Tears for Fears collab, which seemed like such a rad idea at the time)

Last Ninja on the C64 and (to a certain extent) Spindizzy come to mind as well...

Yes! Ant attack came with the Spectrum if I remember correctly!! I did not recall it. Thanks. It was an incredible game.
