Thanks for fixing it.

This reminds me of the game Defender (atari) if it looked nicer and was way more playable. 

First off, I missed the instruction screen because I was trying to adjust the window. Putting it on a timer instead of a button press closing it may have been a bad choice.

The pink projectiles were a little hard to see with the pink landscape behind them. If this was intentional to make me use only half the screen and only risk the lower portion when things get really bad then that's perfect because that's exactly how I played.

The music matches the game very well. That theme combined with the star field drifting by as I fly past alien ?clouds? and unknown opponents makes me feel very alone. Not many games can set and maintain an atmospheric feeling of  alone-ness. The only other one I can think of right now is playing Minecraft alone at 3am.

Once I learned all the enemy ship types and behaviors, it was quite an absorbing game.

One bug I must note: This may just be a feature of your re-release to fix my error, but the game does not reset properly after each death. Some ships and power pickups do not disappear, letting your new ship pick them up. If this was intentional, the fact that not everything stays hides this fact.
