IGN writes: "For a $0.99 iPhone game, GeoDefense is one heck of a title, and even at the eventual $4 mark it's well worth the buy. It's an extremely difficult game, and one that will really require players to try each level dozens of times through to complete or fully master, and even longer once high scores become a factor. It's a shame there isn't online leaderboards, and a few little changes would go a long way (hit zones for buttons is a little small, specifically with the pause and "advance wave" button) but for the most part GeoDefense is a well presented, well designed game that ranks up there with the best TD titles on the platform. Updates would be nice, but a sequel is mandatory. I know you're reading this David".
