Having played this game on the new Amstrad I looked forward to trying it on the Electron too. What a disappointment! The good detailed graphics and attractive screen layout had become crude block effects in very few colours. It didn't even look like the same game. This company always supplies a 'screen shot' from the game on the cassette sleeve, but in this case it isn't even accurate.
The aim of the game is to shoot the wandering proton in the nucleus of the atom while avoiding the electrons which circle it. It's fairly fast but far slower than on the other machine. At the same time as shooting the proton you also have to shoot away the debris which encroaches from the sides of the screen.
All told this is a good game concept which has been very poorly implemented on this machine. The instructions are only fair, being a little too short but the keys are appropriate.
Quite honestly, if this is the best that Romik can do with the Electron I don't why they bothered.
