It's awesome! Looks and plays really nice.
The health mechanic feels close to Blargis game Bloodthief in a sense, unlike his implementation though we die as soon as we get to 0HP.
I wonder though if getting closer to his implementation could make the game even better (personal opinion).
It would be awesome to not automatically die, but still survive at 0HP unless you get hit one last time. Could make for an even more nervous gameplay, and you'd still need to be careful about not missing enemies to not get close to that fatal threshold.
Great execution as it is though, awesome job!!!
