Please take a look at this

at 37:03 when the balloon ran out, it just immediately filled up to 200.
to be frank i have played seal for quite some time but i don't know that such feature was exist not to mention when the marble window is still highlighted. and i have zero video editing knowledge but when you watch closely, all things were moving so fluently as if it's natural
for 200 to be number before 0 but i can't say for sure...

so can anyone of you explain what exactly happened here?
