It's not a particularly substantial arcade game and it's pretty stiff to control, but I like the general mechanics. There are way worse arcade games out there.
I was obsessed with this game as a kid despite never making it that far. Slinging the shield around honestly still feels pretty satisfying. I'm pretty sure I remember this game having a single life and no saves, making it very difficult to get to the end.
The Adventure of Kid Kleets in the US. Unlike 3 Ninjas Kick Back or whatever this game IS developed by the British, and it has all the telltale signs. Kid Kleets is a horrible little goblin.
