I like stacking up my defenses and full screen mode really takes the experience up a notch. The thing that bothered me was not seeing what was attacking us; I just see lasers coming from the top of the screen so I shoot towards the lasers. Would feel a lot more satisfying if I could see what I was shooting and see it get destroyed... Not sure if that actually happens and I'm just not getting to that or maybe something else is going wrong?
It says in the instructions to use the right mouse button to drag the screen around.
Needs resolution settings
Doesn't the full screen button work?
