I passed all the levels. On 9th and 10th level you are fighting against 4 different bosses in a row. On 11th you fight against all 8, one by one... And the last level never ends, the bosses keep coming randomly, you get energy and armor after each of them. I have kept killing them for hour and a half and gave up. One more thing, I think it's impossible to upgrade hero to level 50, 60 or more. It's getting harder and harder after each level you get. It would probably take days and days of gathering points. I succeeded to level 18.
Can you give a more detailed explanation? I tried that and it didn't work!
