Boring - zzzzzzzzzzzzzzzzzzzZZZZZZZZZZZ ZZZZZZ!
Unlike the other reviews I found this game boring and repetitive. The energy ran out alot so I had to keep going back to the primary weapon. Pulling back the energy thing to fire it was very annoying and I found the energy exploded alot 'in my face'. There was not enough room on the left of the screen to drag the cursor all the way back. Putting tanks as the enemy waves was a bit stupid as tanks do fire missiles aswell - Not in this game <.< (Something like trucks with bombs on would be better.
You spent too much time on little details (e.g. the fonts) and not enough time on the game play.
