The toughest part of the extra level was the part where there were two lasers (one stationary, one moveable) firing in the same area at different cycles.

The engineering notation is off by a magnitude of 3. The game sticks to shorthand notation up to Dec, which is e+33. What comes next, 1000 Dec, should be 1e+36, but the game notes it as 1e+33.
Buildings ought to hinder movement, or at the very most, deal some damage for each second of contact. They ought not to kill the team instantly upon touching.
