Don't think I've commented on a game before but I'm enjoying this one greatly and just watched the you tube video. Great game, If I had to say what improvements I would like for upgrades or maybe in a sequel. More defined stats and bigger advantages for using other units. Maybe not advantage more of a reason to use them. Right now I find I mainly use rabbits and then a dragon or two. Any other units are just thrown in for fun as range damage wins out. An who needs melee units or a really strong shield character (turtle) if you kill most things before they get to you or can knock the back and delay them from getting to you in the first place. Or just maybe adjusting more enemies so they cant be knocked back or they are very strong against ranged attacks.
