Alien Storm

Alien Storm opens on a dark blue cliff face beneath a field of stars, with its logo in misty green and lightning-struck purple. A sharp blue and gold warship hovers in the middle, engines burning.

The instruction appears across the middle of the screen as soon as you start, typo included: drag to move. That is all you do, because the ship fires on its own with no button needed.

Enemies arrive in waves of spiky, one-eyed creatures, each carrying its own green health bar, and they drift steadily down towards you. Your own health is shown as an orange bar just above your ship.

Three green gems at the top of the screen show your lives, with a pause button on one side and sound on the other. Coins drop through the field as you fight, waiting for you to fly over them.
