Blast is a simple game. The action is set in a group of large underground caverns, each enclosed by a rocky wall.
You are in control of the latest two-colour pear-shaped space rocket which can move and fire at the same time.
Anyway, shoot out the flashing circles, take out the limpet guns, 'blast' through walls of spheres and... er, that's it.
Although it is simple, it is addictive and to me this counts more than the fact the graphics are bad and the sound added for reason of necessity and not for creativity.
The idea is to fly around not hitting anything and shoot everything before moving to the next screen. The space ship pretends to obey the laws of physics but does not and this actually makes it quite good fun.
There is nothing new or exciting about Blast, it's just one of those games people buy, play and then forget. I didn't buy it but I've played it and though I haven't forgotten it yet, I have doubts as to whether I will be able to remember it next month.
