From Vega 3 via deepest, darkest Wales comes a particularly nasty corrosive green slime ready to splat your QL.
You control a spectral-looking character, strangely reminiscent of the ghostly creatures in Pac-Man around more than 60 screens, charging after pyramids while being chased by the slimes. Steps, stairs and twisting paths must all be negotiated.
If you've been trying to think up things to do with your dusty QL of late, then this is quite a nice way to pass a few hours.
