Lol - didn't think it would work in firefox on android, but it does - kudos! This takes me back, as the gameplay is almost exactly the same as the game for the Psion Organiser II (which had a 2 line screen) which you had to laboriously key in from the back of the manual. Except in that one, IIRC (err, 30 years ago) you could choose when to move back from the top line, and the missiles gradually came faster and faster.
