Here's an old shoot-'em-up that uses the 'build up on your weaponry' method of play. Shoot the oncoming alien swarms and collect the bonus stars that appear after an enemy ship has been destroyed - these supply such glorious things as lasers, shields and a side shot!
Slap Fights real problem is too much detail in the background - intricate and the same colour as the fighter itself - which makes playing unenjoyable as you can't see what's going on. A bit of animation would have helped but each sprite stays exactly the same throughout.
Sounds are few and when you do hear something it isn't worth the wait, just a couple of puny effects when you fire or get shot and no tune on the title screen.
A very run of the mill shoot-'em-up: the gameplay has been copied so many times in other games you wonder why they keep producing them! Thumbs down.
