Congrats, well done what you did in 4 hours! The helis are very large, it would be nicer if the action was zoomed out. Pity you didn't finish it enough for it to be challenging. As it is, can overrun the enemies quite easily.
I was looking at the helicopter script and i realized the i had the wrong object name for the enemy bullets so the helicopters don't lose health. Thanks for the feed back!
