The presentation is great - excellent animation that shows good charm for the various enemies.
Player shooting is very slow and very quickly becomes unnecessary. It would be cool if there was a need for the player to shoot - for example, there's armour on enemies that only the player can remove.
Also, I got to wave 11 and 1000/1000 enemies apparently. If the game is endless, I don't really see the theme coming through.
Certainly enjoyed the game and kudos on the presentation.
