I was nearly the end of Depth 6 and before the Elevator to go Depth 7. There has two gate doors need to open by one switch.
Whatever, I use gun or shoot jar to the switch, the gate doors alway block me outside on the spike keep hurt me until I died.
I can't go through even the gate doors are open !!! I died twice in the front this gate door.

PS: Last time I can passed the gate doors because I jsut let the spike took out some of my red bars.
