Protect the earth from falling asteroids using the Sonic Space Shield. Each asteroid has it's own resonance frequency - get near enough to it and the rock will shake itself apart! Position the Sonic Space Shield using w or d to rotate clockwise, and a or s to rotate anticlockwise. Adjust the frequency setting of the Sonic Space Shield by clicking the mouse button and moving the mouse up or down - alternatively, drag the slider. Fire with the space key.
To-do : 1 - add menu (press 1 to start for now, then green flag on GO screen) 2 - add in-game instructions. 3 - online leaderboard(?) 4 - (maybe) extra levels / ramping difficulty.
