The free version has the same features as the full version, but with ads. Try it first, to make sure it works well on your device. To sponsor the development, go ahead and buy this version.

Cloud Save also works between the free and full versions, so you will not lose any progress.

There are currently 80 levels (blue, red, yellow, rainbow and pink levels) to play, and more are coming!

Collect powerups to buy extra help in form of permanent particle laser, A.I.droid, jumping or extra lives. They can be disabled, if you change your mind. More can be bought with in-app purchases.

Settings include control type and size, music path and music and sound effects volume. Before complaining about the controls, please test them for a while to see which one suits you the best. Also try different control sizes. Also supports game pads, tested with PS3 controller using Sixaxis controller app, Nyko Bluetooth controller and with NVIDIA SHIELD.

The first time the game is started, it will select control type and size based on your device properties. If a gamepad is connected, controls will be hidden and fullscreen is enabled where available. Key mappings are done in the control settings. Gamepad control supports analog joystick for movement.

Touch control types:

Multi touch swipe:

Lower part of display is used to swipe left and right to move the blaster. Right side buttons used for shooting, jumping and superzap. This is the default control for Android 2.2+ devices with true multi touch.

Dual touch swipe:

Similar to multi touch swipe, but for devices without true multi touch. Lower part of display is used to swipe left and right to move the blaster and simultaneously shoot, and swipe up to jump. Right side buttons used for superzap. This is the default control for Android 2.2+ that does not have true multi touch.

Single touch arrows:

Use on devices without multi touch. Controlled with one finger, typically the thumb. Side-arrows area moves while shooting. Up arrow area moves and shoots and jumps when available. Top area superzaps. Center area does not move, the further out on the arrows, the faster movement.

Multi touch arrows:

Use on devices with multi touch. Left side similar to single touch arrows for moving. Right side buttons used for shooting, jumping and superzap. This control type works well with the touch emulated Sixaxis controller.

Multi touch circular:

Use finger to rotate around the circular control on the left side. Right side buttons used for shooting, jumping and superzap.

On Android 4.0+ and devices with soft keys, there is an option to go to real fullscreen mode. Note that this does not work when using touch controls, only when using keyboard or gamepad.

For some older devices, performance may be increased by setting the sound effect volume to zero.

For copyright reasons, the original Tempest 2000 music is not included in the game, but can be automatically downloaded from the settings. It is also possible to select any other music.
