Those who have burned

The fireplace has become hesitant and confused, but still sends you to the location you found in the safe. Your objective: find the skulls that the undead have been transporting. The address leads you to a set of warehouses - could this be what you're looking for? Third level in the "Deadline" collection. If you can't figure out the puzzles, think about what your goal is, what prevents you from reaching it and how to get rid of the obstacle. IMPORTANT: if the third part of the level causes lag, set your graphics to low. The lag is caused by all the wiring between the traps, but setting it to low replaces the wires with straight lines. If the explosions lag, turn off gore. This one's a three-parter, which also means three secret stages! They can be found in the same way as the ones from "Into the Abyss" and "Sinner dinner" - if you haven't figured out what to do yet, it might be worth it to revisit the previous levels an listen to the candles again, as this is the last time they point you towards the secret stages.
