Mr. Do! clone

This is a straightforward clone of the arcade game Centipede. A long slithering alien being gradually moves down a gridded playing area and must be shot out before it can reach the bottom, with the ability to move your ship in all 4 compass directions. Curiously, it doesn't seem to be possible to get a joystick to work in this, despite the chance to define keys.

Eight invaded areas must be brought back under your control in this Commando-style shoot 'em up, which progresses vertically using a flick-screen system. You are armed with a rifle (activated by a short tap of the fire button) and five grenades (used via a longer press), and must not only kill off the enemy forces, but also rescue your comrades who are being lead away.
