you can drag around the mini-gun tower's base and when you press up arrow you cant anymore the mini-gun tower shoots towards your mouse pointer when you have 50 bux and you press buy tower it spawns a dual pistol gunner and you can drag him around and he shoots towards your mouse pointer and when you press space he is not drag-able hen you have 100 bux and you press buy tower it spawns a helicopter, it patrols between 2 points and shoots towards your mouse pointer and the rotor hurts the medic so be careful
i will add more stuff so this isn't full game
