Minter gave it away as a freebie on Llamasoft forums to celebrate getting broadband and it's got me properly laughing out loud. The audio cues all involve blatant aggressive swearing and the "I'm A Wanker" Game Over tune is perfect.
It's also got an "Endurance" survive-with-1-life mode.
I've been getting into all that Kusoge weirdness but I've always known Jeff Minter elicits psychedelic experiences through gameplay best (especially the combination of visual and aural experiences) and the addition of aggressive swearing really does the trick here

If you can find this play it- it's so good I barely noticed it was mouse controlled, eh?
