This is on topic - honest.

Playing lots of Detonator now (thanks to Darkdrium777's sagely advice).

Can't help thinking of the 80s arcade game Tempest - perhaps it could be seen as the great great grandparent of Detonator?

I doubt if many Fury players were even alive when it came out in 1986 - but was just wondering if I was the only one who thought there was a resemblence?
