Work your way down through a cavernous pyramid while blasting really ugly things.
Starting in a room which slowly fills with enemies, you are given the task of blowing them away. If you take too long, a giant eye gets grumpy and turns the enemies into fire. If you kill them fast, the giant eye creates a diamond, which you can use to open one of two doors.
Each level contains two doors in the floor of every level. With the diamonds you receive, you choose which door to open. The left one takes you left through the pyramid, and right goes right. Eventually you will work your way down through the pyramid and hopefully to freedom… or whatever awaits you. I never made it that far.
You see, every level needs to be completed. No matter how far you got last time, you have to begin again from the tip of the pyramid. Fortunately, each successive attempt at completing the game becomes easier as your co-ordination and anticipation grows.
In all, it’s quite a difficult game, though, there are four difficulty modes ranging from “very easy” to “hardest” – I played on Normal and expect the easier modes to be exactly that, and probably to quite some degree. It’s a good game, enjoyable if demanding, but that’s what a good game is, really. Isn’t it?
