I agree with GM637 The same thing happened to me . in there a timer or is it game over 8 miles deep ?
In the ghost form there is a limited amount of time before you die, it's displayed above the head. To stop it you need to collect a life that an enemy drops. If you just died randomly, it's probably I bug that I didn't find during playtesting
Ok ok I get it my bad ... I got to 15 miles deep this time thanks for your explanation
