Endurance training on SWAMP level doesn't seem to work. As soon as it starts the duck makes a beeline for the ceiling. Whether I hold space bar or not, push arrows..nothing helps the poor duck.
Whenever a fight goes down the controls lag out and stop responding. It usually winds up with your tank in a corner, shooting the corner while enemies slowly pick you off.
I agre with Benolds comment. Instead of making the plane default to the top left corner of the screen when the mouse loses focus, please detect which side of the screen the mouse lost focus on and have the plane veer off as far that was as possible, so we can actually hug the right or left walls to pick up items.
