I've had a few requests for a Tower Defense style game. Unfortunately the only ones I could find were ad supported and most of them didn't work on my i776. Here's one that does. It's Tower Wars Time Guardian by InFusio. It seems like a pretty good game with nice graphics, sound and responsive game play. I wish I could figure out how to turn off the help screens that kept popping up though.

There are a few problems with keys that are not mapped properly:
OK doesn't work, use the "Call" key as the OK button.
The right soft key doesn't work press the left soft key for the action associated with the right soft key
For the left soft key press the menu button.

Type: Ad-Supported
Vendor: InFusio/Hovr - Product Page
Data Connection Required: Yes
Supported iDEN phones: All Falcon Series (i776, i465, i9, i290, etc.)
