Datafall is the first of two games from Pocket Money Software that set you up at the bottom of the screen as a catcher trying to catch the falling objects. The idea is simple and in the case of the other title, Bubble Buster, it works quite well.
Sadly, this is a slower and more boring game. There's really very little to say about it at all.
Movement is proportional and therefore tricky to use, the data that is falling is boring and unimaginative, and the game has not got that extra "oomph" to set it above the rest.
On my second game I just kept going until I gave up through boredom!!
Sure, it's well programmed, and has no bugs, but so was "Guess a number between one and one-hundred" (the program which everyone wrote on their ZX81s for those of us who remember that far back!) and it played as well as this.
