I am pretty sure only 8 shot are enough to Make the 2 purples blobs when we are facing dracula
To take down the second form i still don't know.... seems random to me.... does hitting little blobs give health back to dracula u_u?
Proof :
http://youtu.be/cypfAaZheXI i can only shoot 2 bullet per jump
sry for the sh*** quality... i play IWBTG cause the pc can't run other games ;p
EDIT :
OKAY an other bug appear when u change hotkey... "ctrl" to jump and "up arrow" to fire...
with those hotkey u need only 8 bullet to take down dracula's first form... then 95 bullet arn't enough to kill him... i think he is unvulnerable with those hotkeys.. i spent 2 days trying again and again without any result...
then i take default hotkeys and i defeated dracula in 3 try....
