Design

The aMaze MIDlet is a 3D game where the user guides the marble through the maze by tilting the phone until the time runs out.

The aMaze 3D game starts with a simple splash screen, and has a brief information about the game in the info screen. Tapping on the info icon, at bottom-left of the screen, during game menu launches the info screen.

Tapping on the screen, after the splash screen, starts the game. Tapping on the close icon, at bottom-right of the screen, during game menu closes the game.

The aMaze 3D game displays helpful tips, when game playback is idle, to inform the user about different game features. Tapping on the pause icon, at bottom-right of the screen, pauses the game and resuming from the pause menu recalibrates the accelerometer sensor.

The aMaze 3D game is played by tilting the phone to guide the marble through the maze. The screen can be zoomed with the help of pinching gesture, and the zoomed view can be toggled with the help of double tap gesture.
