There are two types of keyboards: AZERTY and QWERTY, and my keyboard's type is AZERTY
Heyy, I managed to beat it with QWERTY keyboard layout, and that was very challenging
Ngl, the boss is really difficult to beat; the blood orb that's following you around seems to be completely random with its spawn (there are times that the orb is instantly back and times that it takes more minutes before doing so)
