Damn good fun
Another great defence game (which I have come to play so often). There was one really annoying thing though, once you upgraded the bullet speed past a point, none of your units aimed properly and shot off-screen...so just watch out for that. Otherwise a very fun and addictive game. I thought the aiming was something new (having the bullet go exactly where you pointed when it was fired and a delay in it reaching there), which made it more challenging and more fun. Graphics could have been slightly better...
Great work overall!
