Why not putting in a paremeter in Water Level event to change it color (putting a number of the JJ2 pallete) or a parameter for limited oxygen (set to 0 to make it normal, put some number, example 10, so if you are 10 seconds in the water, you die)? That would be useful And then, make Bubbles event to make you so if you are in water and you touch it, the oxygen second time until death resets?
