OK, I'll go all-in on this:
2000 AD Comics' Nexus, The computer game.
Made for the Commodore C128 computer (which oddly ran Microsoft Basic), it was a simple single-screen platform shooter with the twist that you could pile up the bodies of your enemies and use them as platforms.
Nice photo!
Also, I do love the Delta (and the Ebre in general, travelled a lot of it's length this year up in Aragón)
