- At the start of each stage, in the first room with the refill station time doesn't start ticking until you open the door - so there is no pressure to move (On later stages if you acquire thermal goggles/heartbeat monitor, you can switch between them in this room and look at the map to spot people and which rooms need to be put out)
- Looking at the map also pauses the clock
- First thing on each level should be to get to the electric room (marked on map), as this makes the electrical fires (grey smoke on e.g. computer desks) much easier (i.e. they don't re-light)
- You can get more than 1 person/cat to "follow" you at a time - so no need to take each person back individually. You can also leave them e.g. in a safe corridor (and take them to the exit later)
- Sometimes better to run in and pull people out of a burning room, rather than try and put fire out first
- On Stage 2 and 4 of each level, "Miss Ion" gives you a mission which rewards a stat upgrade token. These stack between playthroughs and are repeatable (i.e. so you can play the missions on the office level again and again to get upgrades)
