Creditably, this has very probably the best ever title for a Boulderdash game. We've been sent so many of these, it took quite a while to ascertain whether we'd seen this one before. We've not. Probably.

Boomrock is an eight-level demo of the full Shareware version, and features everything you'd expect to find in Boulderdash. Boulders, for example. And dashing. It's also foolishly unpleasant to play, because joysticks are too sweeping to make the pedantic movements so vitally necessary to success, and there's no keyboard option. The game has no surprises at all, years of exactly similar clones mean you can spot the deadfalls, and tricksy chain reactions from half a screen away. There is a great bit where you're desperately trying to outrun amoebae flowing inexorably through a booby-trapped maze, but it hardly makes up for the crushing predictability of everything else.
