Oh, I thought it was a lot. Keep trying mate! Playing less arcade-ish and paying more attention to deliberately dodging incoming attacks, rather than just dashing around to end up right on a trap helped me a lot.
The good news is that it gets easier the more you play both because your skill goes up and your upgrades start to make a real difference in survivability. After my third or fourth clear I could reliably beat Hades every 2 or 3 attempts, depending on the RNG.
