God, how long have I been playing...?
It's when you play a game to the point of slight neck strain that you know it's good.
I had to make myself stop just to write this. Seriously.
It's rediculous how high you can make these bastards go. It also gets easier to keep them at said height when you start getting the better upgrades. But once you purchase them all it kinda turns into one of those 'high score' games. Which are cool, I like me a good game of pac-man... but just not here.
I still need to submit my massive score at the moment, by the way.
Anyways, if you do make another one of these, add in boss fights, more ninjas, more skills, and different level schemes to add variety.
That said, you still get a ten for making my neck hurt and providing me with a good way to spend an hour or two. Bravo.
