Thanks for your support and feedback! Off-screen indicators are a great idea! I can extend our existing targeting indicator system to include indicators for all nearby hostile enemies. In the next patch cycle, we will unleash the inventory system, procedural weapons, and (eventually) new enemies. As such, you can expect a lot of balance changes, including your suggestion. Along those lines, was there anything specific about the flying enemies that make them difficult? I could adjust their AI and flight behaviors to make them easier to fight. Cheers!
