rocket, lasers or machine gun-type turrets with different enhancements such as the ability to slow, stun or deal increased damage .

enemies could have more variety: there could be speedy suicide bombers that deal loads of damage, slow tanky enemies that tank for units behind it, or other type of harassing enemies (stun turrets?) 

need more upgrades and progress path though. The game gets boring without any way to upgrades, which happens roughly 5 minutes into the game. decent game otherwise
