Graphics: I've ran this game on a G1 and a Nexus One. While game detail might have been decent for the G1 resolution, it seems grainy on a higher resolution screen. The game does run smooth. Content: Downside,there aren't that many levels. Flip-side, the variety of mobs and towers to build "hits the spot" (i.e. anti air, rockets, missiles, inferno cannons, slow towers). Replay Value: I don't even know how many level there are. I am on level 40. The only negative is that the game becomes repetitive. You'll end up doing the levels over and over again after you spend your reward points on upgrades. The important thing here is that I've gotten value from what I spent on the game. Overall: 4.0/5.0 In a very weak android game market, I can see why this game shines. The concept of the game is simple, but the execution is near perfect. In the future, I see games that offer more knocking this tower defender from its perch. For the meantime, I recommend this game.
