Takes a bit long, but a nice game. A few updates like upgrading/constructing buildings and upgrading/buying units would be nice. Perhaps create an economy system, buying farms to earn income in order to get units.
An average game has about 40 moves. Unless the program they use is a blitz style, the computer will take a few seconds for each move. This combined with you having to input your opponents moves as you play the computer, then swapping tabs to play the computers move, chances are you will run out of time half way through the 5 minute game.
@Samdc.. people who spend are only temporarily stronger. in the end it comes down to whos willing to grind levels the longest. once you reach 25 ninjas @ lvl 60 each, you save up all karma to buy the best weapons and relics. and there you go, it took longer but your now as strong as those who payed.
