Game Impressions (Kena: Bridge of Spirits)

Good and cute toy. I do not regret the time spent, although the game itself is mediocre. Unfortunately, questions remained after the final.
1. What are the glowing veins on Kena's arm?
2. What about her father?
3. Little is known about Kena's past.
4. Is Kena alive or a spirit?
5. How did that black lesbian die, did she sail away for supplies from the island?
6. I did not understand the moment with little Kena. Is it the past, a hallucination, time travel?
7. Who is the last spirit Kena needs to put to rest? God of Rot? She herself? Father?
