BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.
Install the Channel 3 app from the Google Play Store.
This is NOT a fun game - very repetitive.
You go around punching or flip-kicking into enemies. But the controls aren't that great. And if you miss, you're likely to get hit yourself (and one hit will kill you). Plus, there was one enemy I encountered (I think level 3) where you couldn't move if you ran into him.
You progress by getting the door at the top of the screen to open. Best I can tell, the door opens after you eliminate a certain number of enemies. However, there's no counter anywhere indicating the number needed, so you can't properly plan ahead.
You also can get items by punching and breaking blocks (but then have to be quick enough to punch the item to get it).
