We updated the free demo version to 1.7.3. The full version of Blimps 1.7.3 is currently rolling out to all the app stores over the next few days! In this latest version, we added the Dart Mart and the ability to eliminate the hostile blimps with homing darts. We also renovated the hanger's garage. As always, minor bug fixes and improvements. We hope you enjoy the game. Thanks for playing! -Corinne & Ed
