I really like the concept of reviving or healing the enemies and enjoyed playing it, I'd like to play it again if you keep developing it. I think it could be interesting if there were different types of enemies requiring an specific type of weapon or ammunition to damage them so instead of just changing back and forth between the damaging and healing, you also had to change to the right weapon for that specific type of enemy, I believe it would be a more frenetic approach to the gameplay but I'm curious to see what you come up with the next version of this project. Great work!
