Can't play it!

A nice little game. Good going. It'd be better with sound though. ;)

The approach on the theme is quite obvious. The mechanics are mostly ok, but sometimes it is impossible to shoot the invaders. I like it that the earth can be really destroyed. Also, it needs sounds(enemy approaching, shoot, explosion) and music.

Feels like you have no real chance most of the time as the screen is so small, the crosshair is so slow and the aliens are so fast...

Graphics were nice and it followed the theme very nicely. I like your version of this type of game and i loved the graphics style. Good!

I liked the graphics. Alien AI was pretty good. It was a challenge. I liked that the earth kind of chipped away like that.

I would have liked to see more enemy diversity. Maybe some power-ups would be nice.... double cannon action or soemthing? That would have helped with replay-ability!

Need a way to let the player know where the waves are coming from as when they appear they move too fast to let player react. I liked that you acknowledged the fact that there is no sound in space.
