Very early test of rotation and collision of asteroids; thrust visuals are hand drawn.

Initial experimentation with explosions; added color; threw in hastily-drawn secondary asteroids. Explosions are generated before start of game. Down arrow causes immediate 180 rotation.

Hit testing the game, where red circles indicate collision distance; holding down spacebar fires a torpedo every frame

Introduced braking in this version, experimenting with how to show it; introduced lame alien; made stars move at different velocities to give the illusion of depth,

Added shields;still more experimenting with showing braking;

Improved alien graphic; added alien shooting AI; found a good way to show braking with trailing, fading circles

Experimented with prerendering better explosions at beginning of the game--ended up taking too much time at start of the game but I liked the look; phasers now turn asteroids into glowing orbs that can be collected. This version takes a while to start up.

Added more, but still terrible, AI to aliens; aliens got lame thrust visuals; phasers now create rings that look like old shields instead of glowing orbs; shields have a new angular look. When rings are collected, give some rudimentary feedback

Switched to prerendered swfs of explosions/thrust/braking to improve game startup times; Aliens get good thrust visuals; ring collection feedback is now an implosion.

Added sound effects. At this point game is close but graphics need more attention; prerendered explosions are making the game too big for download

Game closer, but need feedback when phasing asteroids; reduced the size of the game
