Backeroids

Asteroids with a twist, for Github Game Off 2017. Contains six levels, three enemy types,  a rechargeable energy shield, and keyboard/mouse support.

Runs well in FireFox and Chrome, not so much in IE.

Use WASD to move (A/D to rotate, W to accelerate, S to brake) and space to fire; or, use the mouse to aim and fire. Press SHIFT to toggle your shield (it breaks if takes too much damage, recharges when offline), and P to pause.
