That was fun! Mainly because it was so easy
I loved they way game speed was handled in Soldiers - Heroes of WWII (
http://en.wikipedia.org/wiki/Soldiers:_Heroes_of_World_War_II) and the Men of War series (
http://www.menofwargame.com) and wanted to something similar.
You can slow down or pause the game to take out the stress (and think) or speed up the process do avoid waiting time. Unfortunately, the "slow motion" will have no effect on graphic effects like explosions, etc. or sound - maybe later...
