Robbo (itch)

Robbo has been trapped in a hostile extrasolar system. He needs to collect missing screws in order to fix a spacecraft and escape from each of 56 planets.

Control using gestures in vertical or horizontal axis:

• short gesture - turn toward a given direction or move one step forward
• long gesture - go forward
• double tap - fire in current direction (ammo required)
• holding screen (no move) for 2 seconds - restart level (suicide)

At the bottom of the screen there is a status bar with:

• score
• no. of screws to be collected
• no. of lives
• no. of keys
• amount of ammo
• current planet #
