Here is a technical nuance most players miss. The Reflexive version of Chicken Invaders 3 is not the same as the "Standard" version or the Steam version. Reflexive wrapped the game in their proprietary launcher (swf or exe wrapper) that handled the time-trial limits.
: Once the timer expired, the game would lock down. It required a unique activation code tied to a hardware ID or a digital receipt to unlock the full version.
