Love these posts.
In case you haven't already done Ghosts n Goblins: there was also an utterly horrific ripoff/unofficial port of it on the Amiga called "Belial".
The only good thing about it was the actually-pretty-spooky-feeling tracker tune cover of Kraftwerk's "Das Model" as the title/in-game tune, other than that it's a trashfire.
The art is serviceable, if not really taking advantage of what the Amiga can do, but the gameplay is... not great. That person playing has evidently memorised the attack patterns and has mad joystick-waggling skills, because if you don't you don't really get past the first squad of bouncing pumpkins XD
Always actually felt like it was released half done. There's no armour mechanic despite the main character obviously being based on Arthur in underpants-mode, and there are pickups... but there are about two in the whole game and you shoot them rather than walk over them. And they don't do anything but give you a score boost. There's also the matter of how the game can be completed in three minutes.
IIRC we got our copy from some cheap Australian mail-order software house and it arrived with the disk bearing a dot-matrix-printed label, I wonder if it's one of those games where they commissioned the original copy from some kids for a couple hundred dollars? We also had Alpha-1, Caverns of Palle, and Invasion from the same company, and they were similarly C-tier, though they provided some amusement.
