I’ve always got a soft spot for Cauldron, even though the game was stupidly hard and confusing and clunky and OK fine I admit it it’s not that great any more.
But! It was still one of the first games I got for my C64, and I had fun flying around the Defender-style level. It wasn’t until ages later I discovered you could actually enter the houses you flew over all the time, and I kinda wish I didn’t because I’d have much fonder memories of this! Those levels were just stupid!
