Thanks for playing and for the feedback! The safety meter is actually the countdown to collapse, it's just phrased horribly because I had in mind another system and switched last minute. A collapse countdown would make much more sense indeed. There's a secondary timer that will start the collapse if you don't collect the key after 2 minutes but I still wanted to give the player some time to get their bearings, the maze generation algorithm is quite inconsistent and occasionally you get crazy complex dungeons (I should probably work on fixing that :D )
