it sucks!!!!!

realy difficult and repetitive, but a little interesting

1 of the worst games i have ever played.

I liked the game, has good Challenge, but at the end i felt that it was getting impossible.
Intentional or not players like to feel rewarded for making it to such lengths.
There are a few things that would be beneficial, but if i were to list them it would take up half of the screen. Art is decent, music repetitive but spacy, sound effects are Over-bearing and make it so you can hear only them, and nothing else.

a good game, imho. But you should check the difficulty level:
(SPOILER ALERT) everything goes well (even too easy) 'til level 30, then the pink spaceships pop out and the game becomes nearly impossible. But when the big crystal-like ships appear, the game becomes impossible, because even with 5 guns maxed out and 3 bombs you can't stop their attack. You should lower the difficulty a bit.
