Nice gift for x-mas but I would send it back to seller

:-). Some little things might be improved (of course, I know this is a preview).
- player's ship flickers at the beginning of the game
- when new enemy squadron appears, background music is slowing (paused ?) for a little time.
- intro music is not enough apocalyptic to my taste
I am not fan of the vessel shadow. If you keep it,you logically shoud add ones the enemy ships :-).
It's a little bit frustrating that the only way to destroy AA guns is the smart bomb. Maybe extended weapons may help if I can survive more that one minute, who knows...
Anyway, final release could be the best vertical cpc shooter with hardware scroll.
