This game isn't easy for most of us. But, with determination, you can do it. I almost gave up a few times myself. I learned with the dragon, to first strike one nest, and run for shelter to heal. Save and redo. It takes awhile but you will get the hang of it. As LordFess said, keep moving at all times unless you are in a relatively safe area healing.
This game doesn't hold your hand, players need to understand that before buying it. Combat feels unbalanced, makes it more challenging. You need to find the areas you can handle at each level.
