df_base Detention Center re-work the gas room

[bitcores]

In Detention Center there is a room of poison gas (for executing prisoners, allegedly) that the player must pass through to get the Red Key (why it is kept there, I don't know).
There is a force field at the end of the room that disables periodically, and a gas mask in a secret that people rarely find without help. This makes the room frustrating, even if the key is not strictly necessary to complete the level.
Reworking the room so that it is easier to tell the timing of the force field, or just in some other way be less frustrating, would be a plus.
