WOW O.O = Pretty nice game and very simple. Good for boring times. but you should add a little achievements in it.
Like if someone survives 10 seconds or 30 seconds and more and more - and just like that add a few achievements of how many times it has touched that green ball. It'll be fun.
This game is amazing to play but a question arises in my mind - Why can't we go through obstacles when our enemy ships can pass over them?
Well a great games :)
