The idea of saving the bees it self is very nice and must supported. I recommend such type of games to raise this awareness instead of simple gun shooting games, as it could be also very exciting. The graphics and sound effects are very appealing and appropriate for all age sectors. However some enhancement and extra challenges may be required for example healing possibility does not exist also other threats than only chemicals, like hornets or other pests which can cause a serious damage to the hive.
Nice work and creative idea! keep it up
