very nice and awsome 15/10
This game was good but too easy. A thing though i would like to see is permanet powerups that you can buy ever say 2-5 levels and temperary power ups that come out of destroyed enemies. Another good touch would be to add more power ups, and more enemies. This was still a good game though.
Aw, that's awesome.
My only problem with it is that it's too easy. Make your games harder.
Oh, and does this game take advantage of the highscores system provided by MochiAds? I couldn't tell, because I couldn't die.
Could be expanded with a new planet to defend every 10 waves or so - and some additional enemy and bonus types introduced.
Things i would like to see changed:
1. a negative effect when an invader reaches the ground, even if not touching the protection field.
2. powerups coming out of destroyed enemies, not out of the sky.
