This game is so fun...you can do:
- mini-battles
- prevent the stuff from getting to the floor
- attack stacks of blocks with sticks and ball and chains

This is an excellent time waster!

This is the most wonderful time-waster. It has quickly became one of my most used apps.

Amazingly fun. Nice time consumer.

It works very well. Really fun, especially playing with the gravity and moving stuff with zero gravity. :cool: The only problem is that sometimes the top 20 pixels or so that replace the start bar stay there, and I have to restart to get my on screen start menu back. That's the only problem, other than lag (but I'm on a 200MHz OMAP, so that's not the app's fault.) ;)

Yet another great freeware app to give me a reason to use my bad-ass phone. Thanks a bunch!
