EDIT 2: Increased the 'level curve' so at later levels enemies are even stronger. Also, doubled the Demon Lord's HP; was much too easy. Now the game should be much more balanced.
EDIT: Added 5 more levels to bring the total to 15; the last 5 are pretty difficult IMO, check it out!
Also, I made the towers, arrows and barrier stronger to reflect their steep prices. Enjoy!
I made this in about a week, while passing the time waiting to film the cutscenes (the finishing touch) for my epic side-scroller BattleMage.
I got the idea for Castle Siege about a month ago; I wanted ot make a game with enough different upgrades so that all different types of players could enjoy it.
This is my second flash game, and my first submitted to NewGrounds. Hope you enjoy!
