デモニオンII: vs. ミラーワーカーｘ10 (Demonion 2)

Demonion 2: SLG/RTS. Released on 4/28/2014.
Fight vs Mirror Worker x10.
Optional fight in the last floor of the optional dungeon where you fight 10 Mirror copied (Known as Mirror Workers) of your Heroines with significantly higher stats. This fight is easily the hardest fight in the game, and was challenging in its own way although the kill was a little sloppy and some other tactics could be used instead. This setup was done intentionally for game mechanic reasons. Completing the map all in one turn is impossible.
Note:
Special move with voice = Me
Special move without voice = Enemy
There is a 'Congrats screen' displayed after this battle at 6:48, but it's so fast that you probably can't see it.
It's a very well done for a RTS game and the game was rather enjoyable and long. This took me around 3-4 weeks to finish and it's easily 40-50 + hours.
