Wait the abyss is the stage with "the beast" as the boss right? The game is supposed to end there, there isn't another level after it. How did you manage to get even further down?
oh sorry.. I might have confused the names. maybe if I just use numbers. after the forth level there is two extra ones with the curse equipped. but when I get to the sixth one when some enemies tries to use the lasers my game crashes. actually tried to check again and the game crashed in the fifth level too ( the pink one ) so I gues its something about the laser and not the level
