Warp & Warp/Walkthrough

Space World
You will begin each stage in the centre of the Space World. Start out by walking out of the Warp Zone and firing at the Berobero to your left, then the one to your right as it appears, and walk down to fire at the Berobero below you. Once you have done so, the first bonus alien of the stage should appear - and it will most likely be a 500-point Kaeru. If you want more points, you should wait for the Berobero to come closer to the centre of the screen and shoot three of them quickly to make a 1000-point Tako or a 2000-point Kani appear. You should always be mindful of the positions of the remaining Berobero and where they can attack you from; but don't forget that the Warp Zone can be used to your advantage as a shield. When the Warp Zone starts flashing, you can enter it to warp to the Maze World - but if you are already in the Warp Zone when it starts flashing, you will automatically be warped to the Maze World whether you had intended to visit it or not.

Maze World
It takes a little more strategy to kill the Berobero in the Maze World. Timing your bombs correctly is essential here; try to walk in the same direction as a Berobero, only one row or column closer to the centre of the screen. Once you have gotten ahead of it, start laying bombs in advance of the Berobero's arrival. If you think a Berobero will take longer to enter the radius of an exploding bomb, hold the firing button down to increase the time delay on the bomb - you will notice that the bomb changes colour as the time increases. Each time you kill a Berobero in this world, your bombs will become stronger; this obviously makes it easier for you to kill the remaining Berobero, but it also makes it easier for you to blow yourself up! Finally, even if you finish a stage in this world, you will still start the next stage in the Space World.
