We are close to publish the new weapons to Google Play and send for review to App Store. The new weapons would be accessible per 10 finished levels. Each weapon would be possible to upgrade using the coins. it's still free to play, no ads, no in app purchases. Except for continue to play after death by watching once reward video.
Earned this week 30 cents $ by using this way for monetization :) Don't want to break the game play by annoying ads. We are still making the game because of fun despite.
Looking for designer to our team who wants to grow with us.
